Question

what is the solubility in grams of KCL3(s) per 100 ml of water?

For whatever it's worth, there is no salt with the formula KCl3. I expect you mean KClO3. Another for whatever it's worth, is that the solubility varies with temperature. What temperature do you have in mind. You might Google KClO3 and see if Wikipedia list it. If it is on Wikipedia you will find it on the right hand side of the page under properties.
