Atomic weight of hydrogen is 1,008.
Atomic weight of carbon is 12,011.
Atomic weight of chlorine is 35,45.
The sum is the molar mass of CHCl3: 119,369 g.
CHCl3 is a useful compound. molar mass of it is 119.5gmol-1.
Molar mass of CHCl3 is 119.5gmol-1. So mass of 5 mols is 597.5g.
1.75 mole CHCl3 (6.02 X 10^23 mole CHCl3) = 1.05 X 1024 atoms of CHCl3 ====================
molar mass of CHCl3 is119.5gmol-1. so there are 0.49 moles.
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.

Molar mass is a term applied for molecules, not for atoms.

to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)

no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass
1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate).Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate.Molar Mass CaCl2: 110.98g+ Molar Mass H2O: 36.04g*Molar Mass CaCl2 * 2H2O: 147.01gFinding Molar Mass# atoms element A * atomic mass element A = Mass A# atoms element B * atomic mass element B = Mass B... etc.Add up all the mass values and you have the value for molar mass. Do this for both the anhydrate and the water molecules. Add these values together to find the molar mass of the hydrate.Molar Mass Anhydrate + Molar Mass Water Molecules* = Molar Mass Hydrate* Tip: the molar mass of water for all hydrate calculations is 18.02g x number of water molecules. This number may be useful to remember on the day of the test or while doing practice problems.*2. Calculate the percentage of water in hydrate.Divide the molar mass of water by the molar mass of the hydrate, and multiply result by 100%.36.04g147.01g x 100%Percent water in hydrate is 24.52%.
