Question

The volume strength of 3% solution (w/v) of H2O2
(1) 8.99
(3) 9.88
(2) 7.33
(4) 3.77​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{ANSWER :}}}}}$

Volume strength is 9.856.

Explanation:

We are given 3% (w/v) solution of which means that 3 grams of hydrogen peroxide is present in 100 mL of solution. But, (1.76×17)g of is present in 100mL of solution. Therefore, 1000mL of solution gives 9856mL of at STP. = 9.856mL of at STP.
