Answer:
1260 mL
Explanation:
Given data:
Initial volume of gas = 200 mL
Initial pressure = 315.0 KPa
Final volume = ?
Final pressure = 50.0 KPa
Solution:
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
315 KPa × 200 mL = 50 KPa × V₂
V₂ = 63000 KPa. mL/ 50 KPa
V₂ = 1260 mL
