what is the percent CdSO4 by mass in a 1. m aqueous solution

the answer is 17.2%, but im not sure how they got that

i figured to assume a 1 mol CdSO4 amount in 1kg of H20

1 mol/ 1 kg = 1molal

converting to  grams = 208.47/1000 x 100 = 20.8% by mass
 >:(
the book says the answer is 17.2 %


any suggestions?
