MH₂SO₄ = 98g/mol
MNaOH = 40g/mol
MNa₂SO₄ = 142g/mol
n = m/M = 80/40 = 2 moli NaOH
n = m/M = 196/98 = 2 moli H₂SO₄
2 moli .......1 mol
2NaOH + H₂SO₄ ⇒ Na₂SO₄ + 2H₂O
2 moli.......1 mol
2 moli.......1 mol
2NaOH + H₂SO₄ ⇒ Na₂SO₄ + 2H₂O
4 moli ........2 moli
n H₂SO₄ exces = 2-1 = 1 mol
2 moli NaOH......................142g Na₂SO₄
2 moli NaOH.......................x = 142g Na₂SO₄
