A boy and a sled sitting at the top of a hill

a) potential energy
b) kinetic energy

Potential energy I believe

V₂ =  1592.32 L

Explanation:

Given data:

Initial number of moles = 1.54 mol

Initial volume = 383.2 L

Final volume = ?

Final number of moles = 6.4 mol

Solution:

Formula:

V₁/n₁ = V₂/n₂

V₁ = Initial volume

n₁ = initial number of moles

V₂ = Final volume

n₂ =  Final number of moles

now we will put the values in formula.

V₁/n₁ = V₂/n₂

383.2 L / 1.54 mol = V₂/ 6.4 mol

V₂ = 248.8 L/mol ×6.4 mol

V₂ =  1592.32 L
