Answer:
3.2 moles of H2SO4
Step-by-step explanation:
We need to start with a balanced equation. Lets assume the sulfuric acid is formed from sulfur dioxide and water.
SO2 + H2O = H2SO4
This equation is balanced. (Check it)
It tells us that 1 mole of SO2 will form 1 mole of H2SO4, if the reaction proceeds as planned. That's a molar ratio of 1 to 1. They are equal. What moles we react, we should expect the same number of moles of product. [And we need 1 mole of water at the same time]
So if we react 3.20 moles of sulfur dioxide, and keep out lab partner back, we'll obtain 3.2 moles of H2SO4.
