Answer:

Molar mass H₃PO₄ = 97.97 g/mol

Explanation:

To determine the molar mass of H₃PO₄ you sum the molar masses of the element in the compound and you multiply them by the subscripts

H₃PO₄ → Phosphoric acid

Molar mass H₃PO₄ = (Molar mass H). 3 +Molar mass P+ (Molar Mass O). 4

1g/mol . 3 + 30.97 g/mol + 16 g/mol . 4 = 97.97 g/mol

Look for the molar masses of H, P and O in a Periodic Table

H = 1 g/mol

P = 30.97 g/mol

O = 16 g/mol
