What would be the new pressure if 250cm^3 of gas at 760 mmHg is compressed to a volume of 150 cm^3

Explanation:

In order to find the new pressure we use the formula for Boyle's law which is

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new pressure

So we have

We have the final answer as

Hope this helps you

catya your not at all which answer i've seen you do this on another question!
