From a given number of moles of a substance, calculate the mass of another substance involved using the balanced chemical equation.
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul

The molar mass is the mass of a substance divided by its number of moles. The unit that is used to measure the molar mass is grams per moles (g/mol). The mass of gas in a one-mole sample is equal to the molar mass of gas. If the molar mass of gas X was 40 g/mol, this ...
