Explanation:

To find the molar mass of nitric acid HNO3. We need to consider the number of atoms of each element in the formula and then multiply each with the atomic mass .

In HNO3 there are 1 H atom,1 N atom and 3 O atoms

H = 1 X 1 = 1

N = 1 X 14 = 14

O = 16 X 3 = 48

16 + 14 + 1 = 63 g/mol

Answer:

63 g/mol
