What is the Mass of 10 Moles of Sodium Sulphite Na2SO4

Answer: One mole of a compound is equivalent to the Avogadro number. Mole is equal to the ratio of the mass of the substance to the molecular mass of the substance. The molecular mass of sodium sulphite (Na₂SO₄) is equal to the sum of the atomic mass of sodium, sulphur, and oxygen i.e  46 + 32 + 48 = 126. The atomic mass of sodium sulphite is 10 moles multiplied by molecular mass which comes out to be  1260 grams.

Therefore, the mass of 10 moles of sodium sulphite (Na₂SO₄) is 1260 grams.
