Answer:
158 mL
Step-by-step 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.
