Using the ideal gas law in the form of V1/n1 = V2/n2 (where V is volume and n is the number of moles), and given that 0.29 moles of Ar occupies 4.2 L, we can find the volume 0.66 moles will occupy under the same conditions by setting up the equation 4.2 L / 0.29 = V2 / 0.66. Solving for V2 gives V2 = (4.2 L * 0.66) / 0.29, which calculates to approximately 9.6 L.
