250 ml of a sodium carbonate solution contains 2.65 grams of Na₂CO₃ . If 10 ml of this solution is diluted to one litre, what is the concentration of the resultant solution (mol. wt. of Na₂CO₃ =106) [EAMCET 2001]

Question: 250 ml of a sodium carbonate solution contains 2.65 grams of Na₂CO₃ . If 10 ml of this solution is diluted to one litre, what is the concentration of the resultant solution (mol. wt. of Na₂CO₃ =106) [EAMCET 2001]

(a) 0.1 M

(b) 0.001 M

(c) 0.01 M

(d) 10^-4 M


Correct Answer: (b) 0.001 M
