Solve the following parts: a) An aqueous solution of 25 wt% glucose (C,H1206) has a specific gravity of 1.3. If a lab worker needs to feed a mouse in the lab at rate of 20 g of pure glucose a day, how much of the glucose solution in mL the lab worker needs to prepare per day? b) A liquid mixture contains 10 wt% methanol (CH;OH), 20 wt% ethanol (C2H5OH), and water. Determine (a) the mole fraction of each of the three compounds and (b) the average molecular weight of the mixture. c) Calculate the pressure at the bottom of a 30-foot-deep lake in lb/in² and psig. Assume that the lake water has a specific gravity of 1.05. d) Ideal gas law constant has a value of 8.314 J/mol-K. What is the value of the ideal gas law constant in units of Btu/mol-°F?
