Molar mass is the mass of one mole of a substance. A mole is defined as the number of atoms in 12 grams of thecarbon-12isotope. This is always a fixed number, known as Avogadro's number. Therefore, the molar mass of a substance is the mass of Avogadro's number molecules of that s...
We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculations with the molar mass...

Calculating the Molar Mass of a Compound: In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. Answer and Explanation:
Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it's more correct to call the value "relative molecular mass". A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. ...
Once found, the molar mass of the molecule is determined by adding the molar mass of oxygen to two masses of hydrogen, which equals the atoms present in a water molecule. Molar mass has no units, but is often published as grams per mol; this can be pounds per mol if the molar masses...
The mass number is the mass of one atom measured in atomic mass units, or amu. The atomic mass unit was developed to describe the mass of subatomic particles that were too small to measure in conventional units like grams or kilograms. ...
