Question

In the reaction \( 2\text{SO}_2 + \text{O}_2 \rightarrow 2\text{SO}_3 \), if 64 g of \(\text{SO}_2\) reacts completely, how many grams of \(\text{SO}_3\) are produced? (Molar mass of \(\text{SO}_2 = 64 \, \text{g/mol}, \text{SO}_3 = 80 \, \text{g/mol}\))

• A. 80 g
• B. 64 g
• C. 100 g
• D. 128 g

Hint:

Use the mole ratio from the balanced equation and convert moles to mass using the molar mass for stoichiometry problems.
