Answer 1

4804.5 g of SO₂ are needed to the reaction

Step-by-step explanation:

The reaction to produce sulfuric acid is:

2SO₂ + O₂ + 2H₂O → 2H₂SO₄

Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.

If 1 mol of O₂ react to 2 moles of SO₂

Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂

We convert the moles to mass, to know the answer:

75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂
