Suppose a reaction mixture containing 30g of malononitrile, CH2(CN)2 is dissolved in 300 mL of water. The malononitrile is to be isolated by extraction with ether. The solubility of malononitrile in ether at room temperature is 20.0 g per 100 mL. What weight of malononitrile would be recovered by extraction with (a) three 100-mL portions of ether; (b) one 300-mL portion of ether.
