1.	1 ml of 1 M solution is mixed with 999 ml of pure water.
Answer» `10^(-3)` M solution is formed The mass of SOLUTE per ml DECREASES by 1000 times The quantity of solute DECREASE in the solution 10 ml of resultant solutoin contains `10^(-5)` moles of solute Solution :`M_(1)V_(1)=M_(2)V_(2)` `1xx1=M_(2)xx1000=M_(2)=10^(-3)M` 10 ml contains `(10)/(1000)xx10^(-3)` moles `=10^(-5)` moles Quantity of solute in solution remains same but mass of solute/ml decreases by `10^(3)` times
