Question

9. 250 ml of a calcium carbonate solution
contains 2.5 grams of CaCO3. If 10 ml of this 21.
solution is diluted to one litre, what is the
concentration of the resultant solution?

Answer 1

Answer:

9.90099×10^-3 M

Step-by-step explanation:

10 ml caco3 means 1 gram of caco3 .i.e 0.01 mole of caco3 . total volume of resultant solution is( 0.01 l.+1l. =1.01 liter ) now applying molarity formula we get the answer
