Can you show me the steps of how to solve these chemistry stoichiometry problems?

Question

H₂SO₄ + 2 NaOH --> Na₂SO₄ + 2 H₂O

How much Na₂SO₄ could be made if 5 grams of H₂SO₄ and 5 grams of NaOH react?

When 40.1 grams of NaOH and 28.4 grams of H₂SO₄ react, how much H₂O is produced?

Answer 1

Write equation: H₂SO_4H + 2NaOH = Na₂SO₄ + 2H₂O

This is a limiting reactant problem because you have amounts for each reactant.

The easiest thing to do when asked for the amount of product is just to calculate the product from each reactant (assuming the other one is in excess). Whichever one gives you less product is the LR and you have your answer.

5g H₂SO₄ (1 mole / 98.079 g H₂SO₄)(1 Na₂SO₄/1 H₂SO₄)(142.04 g/mole Na₂SO₄) = g Na₂SO₄

5g NaOH (1 mole / 40.00 g NaOH)(1 Na₂SO₄/2 NaOH)(142.04 g/mole Na₂SO₄) = g Na₂SO₄

Do the same thing for Part II.
