Asample of gas has an initial volume of 4.5 l at a pressure of 754 mmhg . part a if the volume of the gas is increased to 8.5 l , what will the pressure be? express your answer using two significant figures.

The pressure will be of 399.17 mmHg.

Explanation:

p1= 754 mmHg

V1= 4.5 L

p2= ?

V2= 8.5 L

p1*V1 = p2*V2

p2= (p1*V1)/V2

p2= 399.17 mmHg

this is a good question! i'll do some research and come back when i have the answer!
