The molarity of the solution containing ...

The molarity of the solution containing 2.8% (mass/volume) solution of KOH is: (Given atomic mass of K=39) is:

A

`0.1M`

B

`0.5M`

C

`0.2M`

D

`1M`

Text Solution

Verified by Experts

The correct Answer is:
B
`2.8%` by mass volume solution of KOH
i.e., `2.8 g KOH` in `100ml` solution
molarity `=(2.8)/(56xx.1)=.5M`
