In the combustion of methane: \( \text{CH}_4\text{(g)} + 2\text{O}_2\text{(g)} \rightarrow \text{CO}_2\text{(g)} + 2\text{H}_2\text{O}\text{(g)} \), what volume of dioxygen at STP is required to completely react with 16 g of methane?

1. 4 moles of \( \text{O}_2 \) / 89.6 L
2. 1 mole of \( \text{O}_2 \) / 22.4 L
3. 2 moles of \( \text{O}_2 \) / 44.8 L
4. 0.5 moles of \( \text{O}_2 \) / 11.2 L
