Answer:
Option A. 107 mL 
Step-by-step explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 150 mL 
Initial pressure (P₁) = 500 mmHg 
Final pressure (P₂) = 700 mmHg 
Temperature = constant 
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's law equation as shown below:
P₁V₁ = P₂V₂
500 × 150 = 700 × V₂
75000 = 700 × V₂
Divide both side by 700
V₂ = 75000 / 700
V₂ = 107 mL 
Therefore, the final volume of the gas is 107 mL.
