(a)
Interpretation:
The molar masses of molecules are given by using chemical formula to be calculated.
Concept introduction:
Molar mass is also known as molecular weight, which is the sum of the total mass in grams of all the atoms that present in a particular molecule. If we know the formula of a compound then we can easily determine the compound’s molar mass. We know that a formula consists of atoms and it is important to count atoms carefully, especially in compounds with polyatomic ions enclosed in parentheses.
