A batch distillation process is used to separate a mixture of ethanol and water. The mixture contains 40% ethanol and 60% water by mass. The distillation is carried out in a still with a capacity of 1000 kg. The initial charge to the still is 800 kg of the mixture. The distillate collected is 300 kg, and the residue left in the still is 500 kg. Calculate the percentage of ethanol in the distillate and residue.
