Question

Assume that fullerene (C₆₀) in the gas phase behaves as a van der Waals gas. The van der Waals constant, b, for fullerene gas is 1.01 x 10^-2  m³ mol^-1. The correct statement about fullerene is:

(1) Radius of C₆₀ molecule is 10 Å.

(2) The volume of one mole of C₆₀ molecules is 8 times of the van der Waals constant, b, of the fullerene gas.

(3) The radius of C₆₀ molecule is 10 nm.

(4) The volume of fullerene gas will always be larger if it behaves as an ideal gas at same P and T.
