How many moles are in 428 L of chlorine gas

19.3 moles

Explanation:

In order to calculate the number of moles of Chlorine gas from the volume, we have to calculate its mass from its known density using the formula:

Density (g/L) = mass (g) /volume (L)

Density of Chlorine gas= 3.2g/L

Volume = 428L

3.2 = mass/428

mass = 428 × 3.2

mass = 1369.6g

Using mole = mass ÷ molar mass

Molar mass of chlorine (Cl2) = 35.5 × 2

= 71g/mol

mole = 1369.6 ÷ 71

mole = 19.2901

mole = 19.3 moles
