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:

0.1M

0.5M

0.2M

1 M

Text Solution

Verified by Experts

The correct Answer is:

Weight of `KOH=2.8 grams`
Volume of solution`=100 ml`
`M=(2.8xx1000)/(56xx100)=28/56=0.5 M`
