Ok guys. I knoiw these questions are easy but for some reason I am really confused when I am doing them. Can someone please explain and help me out how to solve these types of questions? I would appreciate it thanks.
Ques:
What is the molecular weight of an uknown gas if 2.5g of it occupies 2L at 630 torr and a temp of 600K?
I do the P1/V1=P2/V2
Find V2.
Find the density by diving 2.5/2
Then 1.25=Mass/V2
But I never get the right answer and it takes me at least 10 minutes! So what am I doing wrong and are there any shortcuts to this? Thanks in advance.
