Answer 2

Answer:

Molar mass of H3PO4  = 97.99 g/mol (Approx.)

Explanation:

Find:

Molar mass of H3PO4

Given;

Molar mass of H = 1.0079 g/mol

Molar mass of P = 30.974 g/mol

Molar mass of O = 15.999 g/mol

Computation:

Molar mass of H3PO4  = (1.0079)(3) + 30.974 + 15.999(4)

Molar mass of H3PO4  = 3.0237 + 30.974 + 63.996

Molar mass of H3PO4  = 97.9937

Molar mass of H3PO4  = 97.99 g/mol (Approx.)
