1. If 100 mL of a gas, originally at 760 torr, is compressed to a pressure of 120 kPa

at constant temperature, what will its final volume be?

Answer : The final volume will be, 84.4 mL

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

or,

where,

= initial pressure = 760 torr

= final pressure = 120 kPa = 900 torr   (1 kPa = 7.5 torr)

= initial volume = 100 mL

= final volume = ?

Now put all the given values in the above equation, we get:

Therefore, the final volume will be, 84.4 mL

the answer is 303.15 or 303
