Answer 1

Temperature is constant then use boyl's law to calculate volume

We know the Boyle's law

P1V1 = P2V2

where,

P1 = initial pressure = 544 torr

V1 = initial volume = 802 ml

P2 = final pressure = 250 torr

V2 = final volume = ?

we can write above equation as

V2 = P1V1 / P2

Substitute the value

V2 = 544 X 802 / 250 = 1745.15  ml

volume of gas sample will be = 1745.15 ml
