Question

A certain volume of gas was found to be at a pressure of 1200 mm of mercury. When the pressure
was decreased by 500 mm the gas occupied a volume of 2400 cm3
Calculate the initial volume occupied by the gas if the change was done at a constant temperature?

Answer 1

Explanation:

this is the answer please mark as brainiliest

Answer 2

Answer:

1400cm3

Explanation:

Ideal gas equation

PV=nRT

Case 1

1200V=nRT

case ii

2400*700=nRT

V=2400*700/1200

=1400cm3
