Answer:

THE NEW PRESSURE IS 15.5 L.

Step-by-step explanation:

Using Boyle's law which states that the pressure of a given mass of gas is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

P1V1 =P2V2

P1 = 345 torr = 345/760 atm = 0.45 atm

P2 = 760 torr = 760/760 atm = 1 atm

V1 = 34.5 L

V2 = ?

Rearranging the variables, making V2 the subject of the formula, we obtain:

V2 = P2 V1 / P1

V2 = 1 * 34.5 / 0.45

V2 = 15.525 Litres

The volume of the gas when the pressure becomes 760 torr or 1 atm is 15.5 Litres
