Problem

Neon has a molar mass of 20.18 g mol−120.18\,\text{g}\,\text{mol}^{-1}. At 25 ∘C25\,^{\circ}\text{C} and 1.00 atm1.00\,\text{atm}, the molar volume of gaseous neon is 24.5 L24.5\,\text{L}. Solid neon near its melting point (24.5 K24.5\,\text{K}) has a molar volume of 14.2 cm314.2\,\text{cm}^3. Calculate the ratio ρsolidρgas\dfrac{\rho_{\text{solid}}}{\rho_{\text{gas}}} under the stated conditions. Report the ratio to two significant figures.
