What is the molar weight of petroleum ether?
The molar weight of petroleum ether can vary depending on the specific composition of hydrocarbons present in the mixture. On average, the molar weight of petroleum ether is approximately 100 g/mol.
What is the vapour density of the gas if 5.6dm3of a gas weighs 60g at S.T.P?
The molar volume of a gas at STP (standard temperature and pressure) is 22.4 L/mol. To calculate the molar mass of the gas, you can use the formula: Molar mass = (mass of gas / volume of gas) x molar volume at STP. In this case, with a mass of 60g and a volume of 5.6 dm3, the molar mass would be 60g/5.6dm3 x 22.4L/mol = 240 g/mol. Vapour density is calculated as 2 x molar mass, so in this case the vapour density would be 480 g/mol.
How do you find no of atoms if molar mass and density is given?
To find the number of atoms from molar mass and density, you can calculate the number of moles using the molar mass and then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. First, calculate the number of moles by dividing the given mass by the molar mass. Then, multiply the number of moles by Avogadro's number to find the number of atoms.
What is the density of gas that has a gram molecular mass of 32 grams?
To calculate the density of a gas, we need to know the molar mass and the pressure and temperature conditions. Without this information, we cannot determine the density of the gas.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
If given number of moles volume density and molar volume how do you find the molar mass?
To find the molar mass, use the formula: molar mass = (mass/volume) * molar volume. First, calculate the mass by multiplying density and volume. Then, divide the mass by the molar volume to determine the molar mass.
What is the molar weight of petroleum ether?
The molar weight of petroleum ether can vary depending on the specific composition of hydrocarbons present in the mixture. On average, the molar weight of petroleum ether is approximately 100 g/mol.
If the pressure of gaseous chloroform in a flask is 195 mm Hg at 25C and its density is 1.25 gL what is the molar mass of chloroform?
Using the ideal gas law, we can determine that the molar mass of chloroform is approximately 119 g/mol. Given the pressure, temperature, and density of chloroform, you can calculate the molar mass using the formula: (pressure x molar mass) / (gas constant x temperature) = density. Solving for molar mass gives approximately 119 g/mol.
What is the vapour density of the gas if 5.6dm3of a gas weighs 60g at S.T.P?
The molar volume of a gas at STP (standard temperature and pressure) is 22.4 L/mol. To calculate the molar mass of the gas, you can use the formula: Molar mass = (mass of gas / volume of gas) x molar volume at STP. In this case, with a mass of 60g and a volume of 5.6 dm3, the molar mass would be 60g/5.6dm3 x 22.4L/mol = 240 g/mol. Vapour density is calculated as 2 x molar mass, so in this case the vapour density would be 480 g/mol.
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
What is the density of 35 weight percent sulfuric acid how to obtain the molarity for this?
The density of 35 wt% sulfuric acid is 1.174 g/cm^3. To convert weight percent to molarity, you first need to calculate the molar mass of sulfuric acid (98.08 g/mol). Then, using the density and molar mass, you can calculate the molarity (11.9 M) using the formula: Molarity = (wt% * density) / (molar mass).
Calculate the average molar mass of dry air if it has a density of 1.17 gL at 21oC and 740.0 torr?
To calculate the average molar mass of dry air, we can use the ideal gas law. Given that the density of dry air is 1.17 g/L at 21°C and 740.0 torr, we can calculate the molar mass using the formula: Molar mass = (dRT)/(P), where d is the density, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure. Substituting the values and units, we can find the average molar mass of dry air.
What is the density of 3 molar sodium hydroxide in grams per milliliter?
The density of a 3 molar solution of sodium hydroxide is approximately 1.11 grams per milliliter.
How do you find no of atoms if molar mass and density is given?
To find the number of atoms from molar mass and density, you can calculate the number of moles using the molar mass and then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. First, calculate the number of moles by dividing the given mass by the molar mass. Then, multiply the number of moles by Avogadro's number to find the number of atoms.
What is the Mass of an object divided by amount of substance?
The Mass of an object divided by the amount of substance gives you the molar mass of the substance. Molar mass is the mass of one mole of a substance and is expressed in grams per mole.
What is the density in g L of fluorine gas at 7.00 102 torr and 27.0ºC Molar mass of fluorine equals 38.0 g mol?
To find the density of fluorine gas, we first need to calculate the molar volume of the gas using the ideal gas law equation PV = nRT. From there, we can convert the molar volume to L/mol. Finally, we can find the density by dividing the molar mass by the molar volume. The density of fluorine gas at 7.00 x 10^2 torr and 27.0ºC is approximately 1.5 g/L.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
