The sample contains 0.80 mol of
We can use the Ideal Gas Law to solve this problem:.
#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#
We can rearrange this equation to get
#n = (pV)/(RT)#
In this problem,
There are 0.80 mol of nitrogen.
"But sir, what if the pressure unit is in pascals and the volume is in cubic metres instead of cubic decimetres?"
