(1) The molar mass of HNO3 is 63 u.
Explanation:
The "molar mass" of any substance indicates the addition of atomic masses of constituent atoms. In other words, the atomic mass must be added to get the "molar mass" of substance.
Hence, to calculate the molar mass, we must know the atomic masses of component atoms. Here, for the molar mass of nitric acid:
Atomic mass of H = 1.001 u
Atomic mass of N = 14.01 u
Atomic mass of O = 16.0 u
(2) Solution: Calculate the mass of HCl (molar mass = 36.46 g/mol) in 5.00 mL of an HCl solution (density = 1.19 g/mL) that is 37.23% by mass HCl.
