Ethanol can be separated from water through the process of distillation.  With this process, a stream that contains up to 85% ethanol can be generated. 620 moles of an ethanol/water mix with 48% by mole ethanol are distilled to generate a stream with 81% by mole ethanol, with the second stream being pure water.  Calculate the amount of water, in moles, in the second stream. Use one decimal digit in your answer
