The formula of a metal chloride is MCl3 ...

The formula of a metal chloride is `MCl_3` and it contains 20% of the metal.The atomic weight of the metal is approxiamately

A

26.5

B

11.8

C

21.3

D

106.5

Text Solution

Verified by Experts

The correct Answer is:
a
80 g of Cl mixed with 20g of metal.
`therefore` 35.5 g of Ci mixed `=(35.5xx20)/(80)=8.875 g ` metal
`therefore` Equavalent weight of metal =8.875 g
`therefore` Atomic weight of metal of metal `xx` valency
`=8.875xx3=26.5`
