If a sample of 0.29 moles of Ar occupies 3.8 L under certain conditions, what volume will 0.66 moles occupy under the same conditions?

Respuesta :

In order to determine the change in volume, we may use the equation of state for an ideal gas:
PV = nRT

Here, the pressure and temperature of the gas is not changing, therefore, we may simplify the expression to:
Volume is proportional to moles
V / n = constant

V₁/n₁ = V₂/n₂
V₂ = 3.8 * 0.66 / 0.29
V₂ = 8.65 L

0.66 moles of Ar will occupy 8.65 liters of volume.
