    Equation:

    3NH3 + H3PO4 → (NH4)3PO4

    1mol H3PO4 will produce 1 mol (NH4)3PO4

    Molar mass of H3PO4 is 98.0g/mol

    Mol H3PO4 in 6.20g = 6.20/98.0 = 0.06326 mol H3PO4

    Molar mass of (NH4)3PO4 is 149.1 g/mol

    Mass of 0.06326 mol (NH4)3PO4 = 0.06326*149.1 = 9.43g

    Answer: Mass of (NH4)3PO4 produced = 9.43g
