Question
We have 100 mL of 0.1 M KCl solution. To make it 0.2 M,
Options
A.evaporate 50 mL water
B.evaporate 50 mL solution
C.add 0.1 mol KCl
D.add 0.01 mol KCl
Solution
nitial moles of KCl = 
× 0.1 = 0.01
Let x moles of KCl are added , so
0.2 =
or x = 0.01
× 0.1 = 0.01Let x moles of KCl are added , so
0.2 =
or x = 0.01 Create a free account to view solution
