At STP (standard temperature and pressure), which is 0°C (273.15 K) and 1 atm, the molar volume of a gas is 22.4 L/mol. The molar mass of chlorine is 35.45 g/mol. Therefore, the density can be calculated as (35.45 g/mol) / (22.4 L/mol) = 1.58125 g/L, which rounds to 3 significant figures as 3.16 g/L. Therefore, the correct choice is C.
