To calculate the volume of a compound when given its molecular weight and weight, you need to first convert the weight to moles using the molecular weight. Then, you can use the density of the compound to find the volume by dividing the weight in moles by the density. The formula is volume = weight (in moles) / density.

What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
How do you calculate the Fe content in FeO and Fe2O3?
To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.
How do you find the molecular formula for a compound with mass of 78amu?
To find the molecular formula from the mass given, you need to know the individual atomic masses of the elements present in the compound. You will also need to consider the ratios of the atoms in the compound to determine the actual molecular formula. Without this additional information, it is not possible to determine the molecular formula with just the mass.
Where on the periodic table will you find the elements in a molecular compound?
Molecular compounds contain nonmetals, which are on the far right of the periodic table.
What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted.

These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
How do you convert molecules to gram?
You first divide the amount of molecules by avagadros number (6.022x10^23) to find out how many moles you have. Then you find out the molecular weight of the compound. You multiply the number of moles by the molecular weight to give you your weight in grams.
How many micromoles is 20 micrograms?
To convert micrograms to micromoles, you need to know the molecular weight of the substance. The formula to convert micrograms to micromoles is: Micromoles = (micrograms / molecular weight) If you provide the molecular weight of the substance, I can help you calculate the number of micromoles in 20 micrograms.
0.871 moles is how many grams?
Multiply the number of moles by the molecular weight of the compound (or atomic weight for an element) to find the mass in grams.
How do you calculate the Fe content in FeO and Fe2O3?
To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.
How do you find out molecular wt using density?
I'm not exactly positive. But if you know the volume in grams and the mass (giving you density), then you should be able to figure out the molecular weight. The mass is the same as the molar mass, which I would assume is the same as the molecular weight, but I'm not positive.
How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
The kinetic diameter of a molecule is typically estimated based on its van der Waals radius, which can be found in reference tables. Another approach is to use the Lennard-Jones potential parameters for the molecule to calculate its interaction potential with a surface, and then derive an effective size from this interaction potential. These methods can provide an approximation of the molecule's size for practical purposes.
How do you find the molecular formula for a compound with mass of 78amu?
To find the molecular formula from the mass given, you need to know the individual atomic masses of the elements present in the compound. You will also need to consider the ratios of the atoms in the compound to determine the actual molecular formula. Without this additional information, it is not possible to determine the molecular formula with just the mass.
How do you get gram molecular weight?
To calculate the gram molecular weight of a compound, add up the atomic weights of all the atoms in the formula. The result will be in grams per mole.
