**DrBob222**, Wednesday, October 26, 2011 at 1:43pmFirst determine the concn of the molecule. That is done one of two ways;

1)

4.5M x (78/156) = ? or

2) mL1 x M1 = mL2 x M2.

You should get the same answer the same way.

Then you know there is 1 Ca ion is 1 molecule of Ca(ClO3)2 so M Ca ion is the same as M of the Ca(ClO3)2.

You know there are two chlorate ions (ClO3^-) in one molecule of Ca(ClO3)2; therefore, concn of chlorate ion will be twice that of the molecule.
