Question

If a sample of 0.29 moles of Ar occupies 3.8 L at constant pressure and temperature, what volume will 0.66 moles occupy at the same pressure and temperature

Answer 1

8.64 L

Step-by-step explanation:

If 0.29 moles of Ar occupies 3.8L at a specified P and T, then 0.66 moles would occupy:

(0.66 moles/0.29 moles)*(3.8L) = 8.64 L

As long as the pressure and temperature do not change, the volume will scale proportionately to the change in moles.
