Question

a solution of 3.03% H2O2 ,density x gm is prepared. the molarity of H2O2 in this solution is​

Answer 1

ANSWER:   its easy lets understand step by step

mole means weight of compound / mol. wt . of compd. &

1 molar solution means 1mole compund in 1 litre solution

now taking ur compound mol. wt is 34gm

therefore u need 3.4gm in 1 litre solution.

u already have a solution containing 30gm in 100ml solvent so u have to take that much ml which will contain 3.4 gm of compound.

calculating this way:-

100ml has 30 gm

1 ml has 0.3 gm

11.3 ml has 3.4 gm

Therefore take 11.3 ml & make it upto 1000ml.
