Molar mass of HNO3?

A) 63 g/mol B) 53 g/mol
C) 48 g/mol D) 52 g/mol
 
Answer & Explanation Answer: A) 63 g/mol

Explanation:

Calculation of molar mass of HNO3:

Atomic masses of H, N, O are 1, 14, 16 respectively

Now the molar mass of HNO3 is

HNO3 = 1X1 + 1X14 + 3X16

= 1 + 14 + 48

= 63 g/mol or amu.
