250 ~mL of a sodium carbonate solution contains 2.65 ~g of Na ₂ CO ₃ . If 10 ~mL of this solution is diluted to one litre, what is the concentration of the resultant solution?

Options

  1. A0.1 M
  2. B10
  3. C1
  4. D2

Correct answer

B. 10

Step-by-step solution

aligned & M= 2.65 106 1000 250 =0.1 M & M₁ V₁=M₂ V₂ aligned aligned 0.1 10 & =M₂ 1000 M₂ & = 0.1 10 1000 =0.001 M aligned
