Here are the essential concepts you must grasp in order to answer the question correctly.
Molar Volume at STP
At Standard Temperature and Pressure (STP), one mole of an ideal gas occupies a volume of 22.4 liters. This concept is crucial for converting between the volume of a gas and the number of moles, which is necessary for calculating mass.

Molar Mass of CH₄
The molar mass of methane (CH₄) is approximately 16.04 g/mol. This value is essential for determining the mass of the gas once the number of moles is calculated from the volume at STP.

Ideal Gas Law
The Ideal Gas Law (PV=nRT) relates pressure (P), volume (V), number of moles (n), the ideal gas constant (R), and temperature (T). While not directly needed for this specific question, understanding this law provides a foundational context for gas behavior under different conditions.
