Compute the mass of oxygen gas that will combine with 8 g of methane as per the chemical equation `CH_(4) + 2O_(2) to CO_(2) + 2H_(2)O. (R.A.M.: H = 1, O = 16 , C = 12.)`

Explanation

To compute the mass of oxygen gas that will combine with 8 g of methane (CH₄) according to the reaction:

\[ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} \]

we will follow these steps:

### Step 1: Calculate the molar mass of methane (CH₄)
- The molar mass of carbon (C) = 12 g/mol
