Chemistry

This is an ideal gas law problem where you're given pressure, volume, and temperature, and need to find moles. The key insight is that the rigid container means volume stays constant—you don't need to worry about any changes. Just rearrange $PV = nRT$ to solve for $n$, being careful to convert temperature to Kelvin and use a gas constant with matching units (R = 8.314 J/(mol·K) or 8.206 L·kPa/(mol·K) work well here).
