Question 37

The formula of ammonium phosphate is (NH4)3PO4(\text{NH}_4)_3\text{PO}_4(NH4​)3​PO4​.

Calculate the number of atoms that combine together to form 44.7 g of ammonium phosphate. Give your answer in standard form to 3 significant figures. (Relative atomic masses: H=1.0\text{H} = 1.0H=1.0, N=14.0\text{N} = 14.0N=14.0, O=16.0\text{O} = 16.0O=16.0, P=31.0\text{P} = 31.0P=31.0; Avogadro constant = 6.02 × 1023 mol-1)
