Question

A flexible container at an initial volume of 5.12 L

contains 8.51 mol
of gas. More gas is then added to the container until it reaches a final volume of 13.3 L.
Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Answer 1

Explanation:

8.51 moles is to 5.12 L as 'x' moles is to (13.3-5.12) L

8.51 moles / 5.12 L = x / ( 13.3-5.12)

x = 13.6 moles
