1.	The strenth of 10 volume of H_(2)O_(2) solution is :
Answer» 10 68 `60.70` `30.36` Solution :10 volume `H_(2)O_(2)` means, 1 LITRE of `H_(2)O_(2)` will give 10 litre oxygen at STP. `underset(68 g)(2H_(2)O_(2))to 2H_(2)O_underset(22.4 " L at STP")(O_(2))` `because 22.4 L O_(2)` is OBTAINED at STP from `68 g H_(2)O_(2)` `therefore L O_(2)` is obtained at STP from `(68)/(22.4)xx10 g H_(2)O_(2)` =30.36 g Thus, strength of `H_(2)O_(2)=30.36 g//L`.
