A simple question about conversion.
« on: November 03, 2020, 07:18:00 AM »
Hello! so we were given this assignment

What is the volume of gas which exerts a pressure of 845 torr if a 15L gas exerts a pressure  of 700 mmhg?

my solution would be

P1V1 = P2V2

Labelled respectfully as:

P1 = 700 mmhg
P2 = 845 torr
V1 = 15L
V2 = unknown

Notice that the P values are both different one being mmhg and one being torr. My question is which one do I convert to match the other unit is it mmhg to torr or torr to mmhg

How do you convert mmHg to torrs or vice versa?
Also a  very simple question.

No, since they are asking for a volume, not a pressure. I suppose you could play them at their own game and give the answer in different volume units (as long as you got the conversion right), e.g if the answer was 20.5 L you could say 20.5 dm3.
