The moles of na3po4 produced from 3.24 moles of ammonia nacl is

Answer : B). - 1.08 mol

Explanation :

I think question should be "The moles of Na₃PO₄ produced from 3.24 moles of NaCl is"

The balanced reaction is given as

(NH₄)₃PO₄ + 3NaCl → 3NH₄Cl + Na₃PO₄

The stoichiometric ratio between NaCl and Na₃PO₄ is 3 : 1.

Hence,

produced Na₃PO₄ moles = reacted NaCl moles / 3

                                           = 3.24 mol / 3

                                           = 1.08 mol

there are two significant figures.
