### C.
Explanation
## Step 1: Understand STP conditions and molar volumeAt standard temperature and pressure (STP - 0°C and 1 atm), 1 mole of any ideal gas occupies 22.4 liters.## Step 2: Calculate molar mass of gases- Molar mass of
:
- Molar mass of
:
## Step 3: Determine moles in 1 literGiven that 22.4 liters of gas equals 1 mole at STP:
## Step 4: Calculate mass of gases in 1 liter- Mass of
:
- Mass of
:
## Step 5: Compare masses of gasesComparing 0.716 grams of methane to 0.090 grams of hydrogen:
