Answer:

149.09 g/mol

Explanation:

  1. = 1.07 mol N. 14.0 g N.
  2. 1 mole of (NH4)3PO4 contains 3 moles of N. 1.07 moles N x 1 mole (NH4)3PO4.
  3. = 0.357 mol (NH4)3PO4. 3 moles N.
  4. molar mass of (NH4)3PO4 is. 3(14.00) g N.
  5. 12(1.01) g H. 1(30.97) g P.
  6. 4(16.00) g O. 149.09 g/mol.
  7. 0.357 mol (NH4)3PO4 x 149.09 g. =
  8. 53.2 g (NH4)3PO4. 1 mol (NH4)3PO4.

If I'm wrong, correct me please, but I'm sure this correct.

Have a nice night!
