4.07 x 10^-17 ————————————-
(5.6 x 10^-3) (5.8 x 10^5)

How do I solve this exponent function. EX. (6.02 x 10^23) (8.65 x 10^4) -> 6.02[2nd][EE] 23 X 8.65[2nd][EE]4 = 5.20*10^28 or 5.20E28

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
