Hi! I am unsure of how to solve this problem. Thank you!
1. The compressibility factor Z = PV/nRT for O2 at -27.1°C and 537.1 atm is 1.50; at 147.4°C and 95.5 atm, it is 1.02. A certain mass of oxygen occupied a volume of 3.28 L at 147.4°C and 95.5 atm. Calculate the volume occupied by the same quantity of oxygen at -27.1°C and 537.1 atm. 2. The composition of a mixture of gases in percentage by volume is 20.5% nitrogen, 15.7% carbon monoxide, 37.8% water, and the rest sulfur dioxide.

Alexander, who weighs 150lb, decides to climb Mt. Krumpett, which is 5250 m high. For his food supply, he decides to take nutrition bars. The labels on the bars states that each 100-g bar contains 10 g of fat, 40 g of protein, and 50 g of carbohydrates. One gram of fat contain 9 Calories, whereas each gram of protein and cabohydrates contain 4 Calories. Alexander wants to know excatly how many bars to pack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as the uphill climb. How many bars should Alexander pack
Humans are heterotrophs that consume food for energy. These foods comprise of sugars that are broken down by enzymic activity within the body for producing energy. This process, called cellular respiration, occurs according to the chemical equation: C6H12O6(aq) + 6O2(g) 6CO2(g) + 6H2O(l)ΔH = –2802.7 kJ mol –1 a) Write an expression for the equilibrium constant for this reaction.b) At equilibrium, the concentration of the reactants and products are determined as [CO2] = 0.30 M, [O2] = 0.040 M and [C6H12O6] = 0.065 M. Determine the value of theequilibrium constant (Kc) and predict the whether the products or reactants will befavoured at equilibrium.c) Given that the concentrations of the reactants and products at a particular time are[CO2] = 0.65 M, [O2] = 0.020 M and [C6H12O6] = 0.055 M, determine the reactionquotient (Qc).
