 The weight (in gram), of KCl (mol. wt. = 74.5) in 100 ml of a 0.1 M KCl solution is

A

`74.5`

B

`7.45`

C

`0.745`

D

`0.0745`

Text Solution

Verified by Experts

The correct Answer is:
( c)
Molecular weight of KCI (m) = 74.5g
Molarity (M) =` 0.1`
Volume of solution (1) = `100 mL`
`w=(mMV)/(1000)=(74.5xx0.1xx100)/(1000)`
`w = 0.745g`
`therefore` Weight of `KCI -0.745g`
