Question

An unknown volume of 40% (w/w) solution of h2so4 of density 1.4g/ML is diluted until its density become 1.5g/ML.calculate the strength of resulting sol in
(i)%(w/w)
ii) %(w/v)

Answer 1

Answer:

Dear friend,

gram atomic weight of h2so4= 98

40% of weight of the solution= 98;

Gram Weight of solution= 245.

After weakening, volume= 245/1.05=233.33ml.

In this manner, w/v= 98/233.33= 42%

w/w% wtill= 40%
