A gaseous metallic chloride MClx consists of 20.22% of M by mass. The formula of the chloride is?
[M = 27, Cl = 35.5]
MCl
MCl2
MCl3
M2Cl6
Correct answer is C
Percentage by mass of M = 20.22%
Percentage by mass of Cl = ?
100 - 20.22 = 79.78%
Mass given ration of M
M = 20.22/27 = 0.75
Chlorine = 79.78/35.5 = 2.24
Divide by the smallest
M = 0.75/0.75 = 1
Cl = 2.24/0.75 = 3
∴ The formula = MCl3
