Answer to Question #107992 in Chemistry for ainsley

Question

For the reaction 2NaOH + H2SO4--> Na2SO4 + 2H2O, how many moles of Na2SO4 will be produced from 3.50 moles of NaOH if excess H2SO4 is available?

Answer 1

n(NaOH) = 3.50 moles

Solution:

The equation of a chemical reaction:

2NaOH + H₂SO₄ --> Na₂SO₄ + 2H₂O

According to the chemical equation: n(NaOH)/2 = n(Na₂SO₄).

n(Na₂SO₄) = n(NaOH)/2;

n(Na₂SO₄) = 3.50 moles / 2 = 1.75 moles.

n(Na₂SO₄) = 1.75 moles.

Answer: 1.75 moles of Na₂SO₄.
