Hint: Boyle in the mid 1600’s observed that the product of the pressure and volume of a gas are observed to be nearly constant provided that the temperature is kept constant. This is always true in the case of an ideal gas.

P×V=constant

This relationship between pressure and volume of an ideal gas is known as the Boyle's Law.

Complete answer:

Since it is given in the question that temperature can be assumed as constant, we can apply Boyle’s Law.

According to Boyle's Law we know that:

⇒P×V=constant

We can rewrite this as

⇒P1×V1=P2×V2

Where P1 is the pressure at the volume V1

P2 is the pressure at the volume V2

Thus from the given question we can say that:

P1 = 1480 mm

V1 = 500 cc

P2 = 740 mm

V2 = x

Thus we can rewrite the equation and substitute the above values and obtain the equation given below:

⇒V2=P1×V1P2

⇒V2=1480×500740

⇒V2=1000cc

Thus the volume of gas occupied at a pressure of 740 mm is 1000 cc.
