Question

How many moles of nitrogen are there in 7.45 mole sample of ammmonium phosphate?

Answer 1

Answer:

Number of electron of nitrogen/7.45

Answer 2

The number of moles of nitrogen in a 7.45-mole sample of ammonium phosphate is 22.35 moles.

Given: 7.45 mole sample of ammonium phosphate.

To Find: The number of moles of nitrogen in a 7.45-mole sample of ammonium phosphate.

Solution:

The formula of ammonium phosphate is  ( NH4 )3PO4.

So, the number of atoms of nitrogen = 3

By stoichiometry, we can say that,

1 mole of ammonium phosphate has = 3 moles of nitrogen atoms.

So, 7.45 moles of ammonium phosphate has = 3 × 7.45 moles of N

                                                                           =  22.35 moles of Nitrogen

Hence, the number of moles of nitrogen in a 7.45-mole sample of ammonium phosphate is 22.35 moles.
