790 mmHg unknown gas 1.02 L 250 K
At 790 mmHg, an unknown gas takes up a volume of 1.02 L at 250 K.
How many moles of this gas are there?
---------------------------------------------------
PV = nRT
( 참고 https://ywpop.tistory.com/3097 )
n = PV / RT
= [(790/760) (1.02)] / [(0.08206) (250)]
= 0.0517 mol
답: 0.0517 mol
