About 9 grams of chloroform and about 1.36 grams of acetone? Yes, chloroform's molar mass is double that of acetone but same is with volume. 0.79 for acetone and 1.48 for chloroform. Other videos add like 40 ml of acetone per 5 ml of chloroform with 1g KOH. Not sure that so much is needed... Because after that they boil it off which makes the crystals soluble in acetone and then it's a liquid that won't crystallize when added to water.
