Quizplus · Accepted Answer

At STP (standard temperature and pressure), temperature = 0°C = 273.15 K, pressure = 1 atm = 101.3 kPa, and molar volume of any gas = 22.4 L.
The molar mass of Cl2 = 2 x atomic mass of Cl = 2 x 35.5 g/mol = 71 g/mol
The number of moles of Cl2 in 1 L at STP = 1/22.4 mol = 0.0446 mol
The mass of Cl2 in 1 L at STP = 0.0446 mol x 71 g/mol = 3.16 g/L
Therefore, the density of Cl2 gas at STP is 3.16 g/L. Hence, the correct option is C.
