Question

Given the chemical equation,

${\mathrm{K}}_3{\mathrm{PO}}_4+\mathrm{Al}{\left({\mathrm{NO}}_3\right)}_3\to 3{\mathrm{KNO}}_3+{\mathrm{AlPO}}_4$

How many moles of potassium nitrate are produced when two moles of potassium phosphate react with two moles of aluminum nitrate?

Answer 1

From the given equation:

${\mathrm{K}}_3{\mathrm{PO}}_4+\mathrm{Al}{\left({\mathrm{NO}}_3\right)}_3\to 3{\mathrm{KNO}}_3+{\mathrm{AlPO}}_4$

1 mole 1 mole 3 moles 1 mole

1 mole of K₃PO₄ produces no. of moles of KNO₃ = 3

2 mole of K₃PO₄ will produce no. of moles of KNO₃=3×2

=6

6 moles of potassium nitrate are produced when two moles of potassium phosphate react with two moles of aluminum nitrate.
