Answer to Question #179225 in General Chemistry for Brianna

Question

How many grams of H2SO4 are produced from 32.8 grams of NaOH?

Answer 1

Equation for the reaction will be

H₂SO₄+2NaOH→Na₂SO₄+2H₂0

Mol ratio 1:2:1:2

Number of moles of NaOH used=32.8/40=0.82 moles

This means number of moles of H₂SO₄ used=0.82/2=0.41moles

and Na₂SO₄=0.41 moles

H₂SO₄ Used in grams =98grams/mol x0.41 moles=40.18 grams

Na₂SO_4 produced in grams=142g/molx0.41moles=58.22 grams
