Question

What is the empirical formula mass of Nitric acid ? 


(a) 78 g/mol

(b) 98 g/mol

(c) 58 g/mol

(d) 63 g/mol​

Answer 1

Answer:

The molar mass of the chemical substance is equal to the sum of the atomic mass of the individual atoms.

Given

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.

Explanation:

mark me brainlist please....

Answer 2

Answer:

63 g/mol is ur answer...

Explanation:

atomic mass of hydrogen is 1 u

atomic mass of nitrogen is 14 u and oxygen is 16.

so Nitric acid formula is HNO3 ....

ur answeris equal to H is one. so. 1 + nitrogen is one so 14+ oxygen is three so 16 x 3 = 48

so ur answer is 1+14+48= 63 ..
