Question

Which is the correct mole ratio of

Answer 1

The correct mole ratio of K₃PO₃ and KNO₂ in the chemical reaction is 1 : 3

Balanced equation

3Mg(NO₂)₂ (aq) + 2K₃PO₃ (aq) -> Mg₃(PO₃)₂(aq) + 6KNO₂(aq)

from the balance equation,

• The number of mole of K₃PO₃ = 2 moles
• The number of mole of KNO₂ = 6 moles

How to determine the mole ratio of K₃PO₃ and KNO₂

• Number of mole of K₃PO₃ = 2 moles
• Number of mole of KNO₂ = 6 moles
• Mole ratio of K₃PO₃ and KNO₂ =?

Mole ratio = mole of K₃PO₃ / mole of KNO₂

Mole ratio of K₃PO₃ and KNO₂ = 2 / 6

Mole ratio of K₃PO₃ and KNO₂ = 1 : 3
