Question

what pressure will be needed to lwave the vloume of 77.4L ay helium at 98.OK pa to a vloume of 60.0L

Answer 1

Answer:

P₂ = 126.42 kpa

Explanation:

Given data:

Initial volume = 77.4 L

Initial pressure = 98.0 Kpa

Final volume = 60.0 L

Final pressure = ?

Solution:

Formula:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the values in formula.

P₁V₁ = P₂V₂

98.0 kpa × 77.4 L  = P₂× 60.0 L

7585.2 Kpa.L = P₂× 60.0 L

P₂= 7585.2 Kpa.L/ 60.0 L

P₂ = 126.42 kpa
