At a constant temperature the pressure on a 10.0L sample of gas is charged from 1140 torr to 1.00 atm. What is the new volume of gas sample?

15 L

Explanation:

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

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 1 atm

Final volume (V₂) =?

Recall:

1 atm = 760 torr

The new (i.e final) volume of the gas can be obtained as follow:

Initial volume (V₁) = 10 L

Initial pressure (P₁) = 1140 torr

Final pressure (P₂) = 760 torr

Final volume (V₂) =?

P₁V₁ = P₂V₂

1140 × 10 = 760 × V₂

11400 = 760 × V₂

Divide both side by 760

V₂ = 11400 / 760

V₂ = 15 L

Therefore, the new volume of the gas is 15 L

the answer is c i believe
