# A student is provided with two separate rigid containers, each holding an equal mass of a pure gas. Container 1 holds a \(64.0 \text{ g}\) sample of \(\text{SO}_2\text{(g)}\) (\(\text{molar mass } 64.1 \text{ g/mol}\)), and Container 2 holds a \(64.0 \text{ g}\) sample of \(\text{CO}_2\text{(g)}\) (\(\text{molar mass } 44.0 \text{ g/mol}\)). What is the total number of moles of oxygen atoms present in Container 1?

A student is provided with two separate rigid containers, each holding an equal mass of a pure gas. Container 1 holds a \(64.0 \text{ g}\) sample of \(\text{SO}_2\text{(g)}\) (\(\text{molar mass } 64.1 \text{ g/mol}\)), and Container 2 holds a \(64.0 \text{ g}\) sample of \(\text{CO}_2\text{(g)}\) (\(\text{molar mass } 44.0 \text{ g/mol}\)). What is the total number of moles of oxygen atoms present in Container 1?

- **A.** \(2.00 \text{ mol}\)
- **B.** \(2.91 \text{ mol}\)
- **C.** \(3.00 \text{ mol}\)
- **D.** \(4.36 \text{ mol}\)
