Find the % w//v " of " ''10V'' H(2)O(2) ...

Find the `% w//v " of " ''10V'' H_(2)O_(2)` solution

A

`10.2%`

B

`3.03%`

C

`22.4%`

D

`5.04%`

Text Solution

Verified by Experts

The correct Answer is:
(B)
Molarity `"(M) of solution" =("volume strength")/(11.2) = (10)/(11.2)`
`%((w)/(v)) = ("M" xx "mol. wt. of solute")/(10) = (10)/(11.2) xx (34)/(10) = 3.03%` .
