Question
250 m l of a sodium carbonate solution contains2.65 gm. of Na2CO3. If 10 m l of this solution is diluted to one litre. What is the concentration of the resultant solution?
Options
A.0.1 M
B.0.001 M
C.0.01 M
D.10-4M
Solution
Molarity of solution M1 = 
= 0.1 M
M1V1 = M2V2
0.1 × 10 = M2 × 1000
M2 =
= .001 M
= 0.1 MM1V1 = M2V2
0.1 × 10 = M2 × 1000
M2 =
= .001 MCreate a free account to view solution
