How many moles of water are on 72.08g of H2O?
The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.
What is the molar mass of C6Cl6?
The molar mass of C6Cl6 (carbon tetrachloride) is approximately 253.73 g/mol. This can be calculated by adding the atomic masses of carbon (12.01 g/mol) and chlorine (35.45 g/mol) for each atom in the compound.
How do you determine if a compound is a solid liquid or gas based on solubility?
There is no uniform constant for the solubilities of gases in liquids. Each compound has a solubility unique to itself. However, the general rule of thumb is that "like dissolves like." Water is a polar molecule, therefore it will readily dissolve polar gases such as hydrogen chloride gas (HCl). When this happens hydrochloric acid is formed. Carbon dioxide (CO2) is what is dissolved in water to yield the weak acid carbonic acid, which is also what gives soda its fizz. Because CO2 is not polar it does not dissolve in water very well. Only 0.145 grams of CO2 can be dissolved in 100 mL of water compared to HCl's 72g/100mL. Carbon dioxide would more willingly dissolve in a solvent such as benzene because benzene is nonpolar just like CO2.
How many moles are in 72g of Calcium Sulphate?
To calculate the number of moles in 72g of Calcium Sulphate (CaSO4), we need to know the molar mass of CaSO4, which is approximately 136.14 g/mol. Then use the formula: moles = mass / molar mass. So, moles = 72g / 136.14 g/mol ≈ 0.53 moles of CaSO4.

What is the density of an object whose mass is 72g and whose volume is 36cm3?
density = mass / volume = 72 g / 36 cm³ = 2 g/cm³
What is 72g in pounds?
Far less than 1 pound. 72 grams is 0.15 pounds.
How old is a Browning serial number 72G 96937?
The 72G prefix dates your browning auto-5 light weight shotgun to 1972.
What is the GCF of 54gh 72g?
The GCF is 18g.
How many mg are in 72g?
72,000 mg
What is a 72g 24421?
The prefix of 72G indicates that you have a Browning auto-5 light weight shotgun that was made in the year 1972.It is chambered in 12 gauge.
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of ovygen?
The balanced chemical equation for the reaction of hydrogen and oxygen to form water is 2H2 + O2 -> 2H2O. Based on the equation, for every 2 grams of hydrogen, 64 grams of oxygen are needed to form 36 grams of water. Thus, if 8 grams of hydrogen react completely with 64 grams of oxygen, the total mass of water formed would be 36 grams.

How do you convert 72g to mg?
Multiply by 1000 =72,000 mg
How do you calculate the number of moles from the mass?
This is a generic answer with an example of how to solve this kind of problem. You can use the technique given here to find the answer to your particular problem. First you need to find the molecular weight of the compound. Once you've done that, then you simply divide the mass of the compound (in grams) by the molecular weight of the compound (in amu). The result is the number of moles. For example: Water (H2O) has a molecular weight of 2 * 1.0 (for the two hydrogens, 1 amu each) + 1 * 16.0 (for the oxygen, 16 amu) or 18.0 amu. So if I have 27.0 grams of water, then I have 27.0 / 18.0 = 1.5 moles of water.
