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.
To calculate the molar mass of a compound, first determine the atomic masses of each element present in the compound. Next, multiply the atomic mass of each element by the number of atoms of that element in the compound. Finally, sum the products of each element to obtain the molar mass of the compound.
The empirical formula of a compound is the simplest whole-number ratio of the elements in the compound. It is determined by dividing the molar ratios of the elements in a compound by the smallest molar value to obtain whole numbers.
The molar mass of the compound CaBr2 is 199.9 grams per mole.
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)
Molar mass depend on the ,mass,type and number of atoms in molecules of compound.

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)
