Question

Which of the following best defines the molar mass of a substance?

Answer 1

Total mass, in grams, of all the particles in one mole of the substance

Explanation:

• Molar mass is defined as the ratio of the given mass of the substance to the amount of the given substance in moles.

The formula is, Molar mass =$\frac{Given mass}{Number of moles}$

• By definition, these are mass in grams of all the particles in one mole of the substance. The unit of molar mass is g/ mol
• The molar mass of the element is what we see in the periodic table. The periodic table is constructed according to the atomic number of each elements and there represented the atomic mass, which is the molar mass of the elements.
