A gaseous metallic chloride MCl consists of 20 ... - JAMB Chemistry 2020 Question
A gaseous metallic chloride MCl consists of 20.22% of M by mass. The formula of the chloride is?
[ M = 27, Cl = 35.5]
A
MCl
B
MCl\(_2\)
C
MCl\(_3\)
D
M\(_2\)Cl\(_6\)
correct option: c
***
| M | Cl | |
| % composition | 20.22 | 79.78 |
| Atomic mass | 27 | 35.5 |
| Mole ratio | 20.22 | 79.78 |
| 27 | 35.5 | |
| 0.75 | 2.25 | |
| Divided | 0.75 | 0.75 |
| 1 | 3 |
Which gives formula of the Chloride = MCl\(_3\)
