Isabell · Answer 1

n₂ = 9.4 mol

Explanation:

Given dа ta:

Initial volume of gas = 8.15 L

Initial number of moles of gas = 4.51 mol

Final number of moles = ?

Final volume of gas = 16.9 L

Solution:

Formula:

V₁/n₁ = V₂/n₂

V₁ = Initial volume

n₁ = Initial number of moles

V₂ = Final volume

n₂ = Final number of mole

Now we will put the values.

8.15 L / 4.51 mol = 16.9 L / n₂

n₂ = 16.9 L * 4.51 mol / 8.15 L

n₂ = 76.22 L. mol / 8.15 L

n₂ = 9.4 mol
