Question

Calculate the density of chlorine gas in g/l, at stp.

Answer 1

3.2 g/L

At STP : p = 1 atm and T = 273.15 K
molar mass Cl2 = 70.906 g/mol

d = molar mass x p/RT = 70.906 x 1 atm / 0.08206 x 273.15=3.16 g/L

Answer 2

Answer: The density of chlorine gas is 3.17 g/L

Step-by-step explanation:

At STP:

1 mole of a gas occupies 22.4 L of volume.

Molar mass is defined as the mass of 1 mole of a substance.

Molar mass of chlorine gas = 71 g/mol

To calculate the density of chlorine gas, we use the equation:

`Density=(Mass)/(Volume)`

Mass of chlorine gas = 71 g

Volume of chlorine gas = 22.4 L

Putting values in above equation, we get:

`\text{Density of chlorine gas}=(71g)/(22.4L)=3.17g/L`

Hence, the density of chlorine gas is 3.17 g/L
