Question

What is the molar mass of H₃PO₄? (H=1.008, P=30.97, O=16.00)
Options
A 94.97 g/mol
B 97.99 g/mol
Correct Answer
C 98.00 g/mol
D 100.00 g/mol
Correct Answer

Option B is the correct answer.

Detailed Explanation

Molar mass of H₃PO₄ = (3 × 1.008) + 30.97 + (4 × 16.00) = 3.024 + 30.97 + 64.00 = 97.99 g/mol.

Hint
