A sample of gas in a 10.0 - L container exerts a pressure of 1.2 atm. Calculate the pressure exerted by the gas if the volume is changed to 15.0 L at constant temperature.

We use Boyle's law
p1V1 = p2V2
1.2 x 10.0 = p2 x 15.0
p2 = 0.80 atm

pV = nRT
Givne p and V initially cal them p0 and V0. Told T is constant. SO
p1V1 = nRT =p0V0 ---> p1 = p0 V0/V1 = 1.2*10/15 = 1.2 *2/3
p1 =0.8 atm

Divide the style of grams via each and every compound's molar mass. this provides you with the style of moles of that compound, that then you definitely multiply via 22.4 to get your answer, in liters. Do the maths your self, youngster.

P1V1=P2V2....plug in the numbers to get ur new pressure(P2)
