Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

If you wanted to find the total number of atoms for hno3 this nitric acid you just add these up three plus one plus one five atoms in nitric acid hno3

Answer 2

Step-by-step explanation:

Atomic mass of H = 1u

Atomic mass of N = 14 u

Atomic mass of O = 16u

The molar mass of HNO3 is

(1 × 1) +(1 × 14) + (16×3) = 63 u.
