If a gas occupies 12.60 liters at a pressure of 1.50 atm, what will its pressure at a volume of 2.50 liters?

7.56 atm

Explanation:

Boyle's law states that the pressure and volume of a gas are proportional to each other

The formular for Boyle's law is

P1V1=P2V2

According to the question above, the values given are

P1=1.50 atm

P2=?

V1=12.60 litres

V2 = 2.50 litres

Let us make P2 the subject of formular

P2 = P1V1/V2

P2 = 1.50*12.60/2.50

P2 = 18.9/2.50

P2 = 7.56 atm

Hence when the volume of a gas is 2.50 litres then it's pressure is 7.56 atm
