How many grams of a 25% sodium hydroxide solution is required to absorb the volume of sulfur dioxide found in solving Problem 5?

Solution:
1) 2NaOH + SO₂ = Na₂SO₃ + H₂O
2) n (SO₂) = 2n (NaOH) = 2 * 67.2 / 22.4 = 6 mol
3) m (NaOH) = 6 * 40 = 240 g
4) m (solution) = 240 * 100/25 = 960 g
Answer: 960 g
