So iv solved all these problems, id just like someone to take a look at them and see which approach is right.(adsbygoogle = window.adsbygoogle || []).push({});

The question is in the attachment.

first approach is i use molar volume for SATP which is 24.76L and multiply 65L with it

and i get 1609.4L then i use this in the universal gas forumla(i think thats what its called)

PV=nRT

(100)(1609.4) = n(8.31)(298)

(100)(1609.4)/(8.31)(298) = n

second approach i use is where i just use the 65L of volume as is and put it in the equation, since they both are volumes, which one is the right way?

PV=nRT

(100)(65)=n(8.31)(298)

(100)(65)/(8.31)(298) = n

which approach is correct?
