H2SO4 + 2 NaOH = Na2SO4 + 2 H2O How many grams of Na2SO4 could be produced from 4.94 moles of sulfuric acid?

Question

Grateful for any help given!

Answer 1

Hello, Kitty,

The balanced reaction says that we should expect the moles of Na₂SO₄ to be the same as the moles of the sulfuric acid: Their molar ratio is 1 to 1.

So we should expect 4.94 moles of H₂SO₄ will result in 4.94 moles of Na₂SO₄. Convert this to grams by multiplying by the molar mass of Na₂SO₄.

(4.94 moles)*(142 g/mole) = 701 g (to 3 sig figs)
