- A scientist adds 0.450 mol of liquid AB 2 (l) and 0.0100 mol of the vapour AB 2 (g) to an empty 10.0 Lcontainer at 25°C.17. This scenario mimics a situation a 2022 graduate experienced on their APPE last spring: How many milliliters of anhydrous dextrose 10 % (w/v) solution and anhydrous dextrose 2.5 % (w/v) are needed to make three liters of a 300 mOsm/L product.Normality of 20% (w/v) of H2SO4 is
- Q1a-> A sample of hydrogen (H₂) gas was collected over water at 60°C. If the total volume of gas collected was 53.9 mL and the atmospheric pressure was 1.14 bar, what mass (in g) of hydrogen gas was collected above the water? The vapour pressure of water at 60°C is 150 torr. Q1b=> What is the molar mass (in g mol-¹) of a gas which has a density of 1.91 g/L at a pressure of 0.91 bar and temperature 15.3°C? Your answer may not correspond to an actual gas. Do not try to identify the gas.If 124.4 mL of water is shaken with oxygen gas at 0.81atm, it will dissolve 0.0036 g O2. Estimate the Henry's law constant for the oxygen gas in water in units of g mL ^-1atm^-1.If 102.6 mL of water is shaken with oxygen gas at 1.8 atm, it will dissolve 0.0034 g O2. Estimate the Henry's law constant for the oxygen gas in water in units of g mL-1atm-1.
