Answer:
160 g of NaOH
Explanation:
Reaction: 2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O
When a base and an acid react, the produce water and a salt. → Neutralization
In this reaction 2 moles of hydroxide need 1 mol of sulfuric acid to react, it is the same to say that 1 mol of sulfuric acid needs 2 moles of NaOH to react. We convert the mass of sulfuric to moles and we propose the rule of three:
196 g / 98 g/mol = 2 moles
1 mol of sulfuric acid needs 2 moles of NaOH to react
Then 2 moles of sulfuric acid will react with (2 . 2) /1 = 4 moles of NaOH
We convert the moles of base to grams → 4 mol . 40 g /1mol = 160 g
