The volume at STP is 471 L.
Step 1. Calculate the moles of
Step 2. Calculate the volume of
I assume that the gas is at STP (1 bar and 0 °C).
We can use the Ideal Gas Law to calculate the volume.
#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#
We can rearrange this to
#V = (nRT)/p#
