How to calculate percentage impurity in a chemical reaction? (Weight of one of the solute and the gas evolved is given. It is asked to find %impurity of the solute whose weight is given))

Dear student,

There is no direct formula to calculate percentage impurity. First, we need to calculate percentage purity then we have to subtract percentage purity from 100, the resulting answer will be the percentage impurity. 

Percentage purity = Mass of pure productMass of the sample or impure product×100
Percentage impurity = 100 - Percentage purity

Please provide a clear question of percentage impurity with data such that, I can explain you properly.

Look forward to hearing from you again!

Regards
