How many grams of NaOH will be required to Prepare 500 gram solutioncontaining 10% w/w NaOH solution ?

A

0.5 gram

B

100 gram

C

5.0 gram

D

50 gram

Text Solution

Verified by Experts

The correct Answer is:
D
`%(w)/(w)=(100xx"mass of solute")/("mass of solution")`
`therefore 10=(100xx"mass of solute")/(500)`
`therefore` Mass of solute `= (10xx500)/(100)=50` gram.
