Question

Calculate the molar mass of (a) Ethyl alcohol (b) Nitric acid​

Answer 1

Answer:

molar mass of ethyl alcohol is 46.069 g/mol

molar mass of nitric acid is 63.01 g/mol

Explanation:

hope it helps!!

Answer 2

Explanation:

a -> 46.07 g/mol

Because 1 mol of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol.

b-> 63.01g/mol

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.
