Answer 1

The density of chlorine (Cl2) gas at STP is calculated by dividing the molar mass of chlorine by the volume occupied by one mole of gas at STP, which is 3.16 g/L.

Step-by-step explanation:

To calculate the density of chlorine (Cl2) gas at STP (standard temperature and pressure), we'll use the molar mass of chlorine and the ideal gas law at STP conditions. The molar mass of chlorine is approximately 70.90 g/mol (35.45 g/mol per chlorine atom, and there are two atoms in Cl2).

At STP, one mole of any ideal gas occupies 22.4 liters. Therefore, the density (ρ) can be calculated using the formula ρ = mass/volume. Since the molar mass is the mass of one mole, we have:

ρ = (70.90 g) / (22.4 L) = 3.16 g/L

Therefore, the density of chlorine gas at STP is 3.16 g/L.
