Question

5% solution se3.6%ka solutio kaise banaye​

Answer 1

Explanation:

Dear Sir. Concerning your issue about the preparation of 3.5% soln from 5% . You can use dilution law :

C1*V1 = C2 * V2

assume if you want to prepare to the volume of 100 ml, then:

5 % * V1 = 3.5% * 100 , So , V1= 7 ml, that mean you should take 7ml from the stock solution (5%) and completed to the volume (100ml) by deionized water.

Regards,

Thanks

Answer:

There should be such kind of element in the compound which can become vapour when it undergoes either exothermic or endothermic or heat, etc. So, in order, the percentage of a particular solution goes down.
