6.) A solution is made by mixing 138.2 grams of ethanol, C2H6O, (46.069 g mol-1); 103.6 grams of water (18.015 g mol-1), and 80.11 grams of methanol, CH4O (32.042 g mol-1). What is the mole fraction of methanol in the mixture? Calc mol of each 3 mol EtOH, 5.75 water, 2.5 MeOH. Total = 11.25 2.5/11.25 =0.222222 a. 0.02504 b. 0.2222c. 0.2493 d. 0.3333 e. 0.4490 7.)

What osmotic pressure would develop across the membrane if the temperature is 26.0 °C? -4 8.)What is the most important (biologically) and unique feature to the phase diagram of water? 9.) What 4 factors affect reaction rates? Chapter 13 Lecture slide 2 10.) The rate of a chemical reaction in solution can be measured in the units of… a) mol L-1s-1= M/sb) L2mol-1s-1 c) sec L-1mol-1 d) s-2e) none 11.) In a particular study of the reaction described by the equation, 2CH4O(g) + 3O2(g) 2CO2(g) + 4 H2O(the rate of consumption of O2(g) is 0.400 mol L-1s-1. What is the rate of formation of H2O(g g ), )?
