At 1400 mm Hg, a gas has a volume of 350L. What is it volume at stander pressure?

V₂ = 630 L

Explanation:

Given dа ta:

Initial volume = 350 L

Initial pressure = 1400 mmHg (1400/760 = 1.8 atm)

Final volume = ?

Final pressure = standard = 1 atm

Solution:

The given problem will be solved through the Boly's law,

"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

1.8 atm * 350 L = 1 atm * V₂

V₂ = 630 atm. L/1 atm

V₂ = 630 L
