Question

Calculate the molar mass of the substance - Nitric acid, HN0₃.

Answer 1

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.

63 g/mol.
Molar mass.

Answer 2

hey mate Here is your answer,,
mass of oxygen(O)=16
mass of nitrogen(N)=14
mass of hydrogen(H)=1
mass of HNO3=mass of hydrogen+mass of nitrogen+3×mass of oxygen
=1+14+16(3)
=1+14+48
=63.
hope it helps.
