Boyle's Law: P1V1=P2V2 The volume of a gas at 99.0 kPa is 300mL. If the pressure increases to 188kPa, what is the final volume?

158 mL

Explanation:

From the question given above, the following data were obtained:

Initial pressure (P₁) = 99.0 KPa

Initial volume (V₁) = 300 mL

Final pressure (P₂) = 188 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as illustrated below:

P₁V₁ = P₂V₂

99 × 300 = 188 × V₂

29700 = 188 × V₂

Divide both side by 188

V₂ = 29700 / 188

V₂ = 158 mL

Therefore, the final volume of the gas is 158 mL.
