OK. Just the answer: saturated.

I'm guessing that your instructor has asked you to get the answer from a chart k like the one below,

www.dynamicscience.com.au

We see from the chart that the solubility of #"KCl"# at 20 °C is 34 g/100 g water.

# "34 g KCl"/"100 g water"= "8.5 g KCl"/"25 g water"#

Thus, if you add 15 g of #"KCl"# to 25 g water, 8.5 g will dissolve to give a saturated solution, and 6.5 g will remain undissolved.
