The molar mass of any compound contain a number of molecules equal to the number of Avogadro:
6,022 140 857(74).10e+23.
If 6.00g of the unknown compound contained 0.200mol of C and 0.400mol of H, how many moles of oxygen, O, were in the sample?
Divide the mass by the number of moles.
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
The molar mass of the compound CaBr2 is 199.9 grams per mole.
The Stoichiometry of molar concentration follows this simple formula: Mol = Volume (dm³) × Molar Concentration (mol/dm³) Hence: Molar Concentration (mol/dm³) = Number of moles (mol)/ Volume (dm³)
To calculate molar mass, you use the following formula.Molar Mass = Given mass / number of moles.For example if you are given that there is 85 gram of ammonia and it is 5 moles. Then Molar Mass = 85/5 = 17 g.
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.

The molar mass of a compound is equal to 1 mol.
the empirical formula and the molar mass
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
The molar mass of the compound CaBr2 is 199.9 grams per mole.
A mole of a substance contain 6,022 140 857.10ex23 (number of Avogadro - NA ) molecules.A mass (in grams) contain a number of molecules equal to:(given mass x number of Avogadro)/molar mass
253.81 g mol-1
1 mol is equivalent to the molar mass of a compound, in grams.
To calculate molar mass, you use the following formula.Molar Mass = Given mass / number of moles.For example if you are given that there is 85 gram of ammonia and it is 5 moles. Then Molar Mass = 85/5 = 17 g.
The Stoichiometry of molar concentration follows this simple formula: Mol = Volume (dm³) × Molar Concentration (mol/dm³) Hence: Molar Concentration (mol/dm³) = Number of moles (mol)/ Volume (dm³)
