1. How many moles of oxygen gas is required to completely react with 50g of CH4
Step 1: Write the balanced chemical equation for the combustion of methane.
$$\text{CH}_4(g) + 2\text{O}_2(g) \longrightarrow \text{CO}_2(g) + 2\text{H}_2\text{O}(l)$$
Step 2: Calculate the molar mass of $\text{CH}_4$.
Molar mass of C = $12.01 \text{ g/mol}$
Molar mass of H = $1.008 \text{ g/mol}$
Molar mass of $\text{
