If 20g of sodium chloride is dissolved in 100 cm3 of water at 20c is the solution saturated?

I looked up the solubility of NaCl in my copy of The Merck Index and it is listed as 1 gram NaCl dissolving in 2.8 mL water at 25 degrees C. Converting that means that 35.7 g NaCl should dissolve in 100 cc at 25 degrees C. I don't have the solubility for 20 degrees C and I didn't find it listed on the Internet; however, my guess is that 20 g/100 cc would not be saturated.
