The pressure on a 200-milliliter sample of CO2(g) at constant temperature is increased from 60 kPa to 120 kPa. What is the new volume of the gas?

100 milliliter

Explanation:

Initial Pressure P1 = 60 kPa

Final Pressure P2 =   120 kPa

Initial Volume V1 = 200mL

Final Volume V2 = ?

These parameters are related by the following boyle's law which is mathematically given as;

V1P1 = V2P2

Making V2 subject of interest;

V2 = V1P1  / P2

inserting the values;

V2 = 200 * 60  /  120

V2 = 100ml
