A 0.75-L bottle is cleaned, dried, and closed in a room where the air is 24°C and 50.% relative humidity (that is, the water vapor in the air is 0.5 of the equilibrium vapor pressure at 24°C). The bottle is then brought outside and stored at 0.0°C. (a) What mass of liquid water condenses inside the bottle?
Compute the final pressure in the tank if nothing else is altered in the surroundings. (The two gases do not react)
If 0.80 g of a gas occupies 295 mL at 25C and 680 mm Hg of pressure what is the molar mass of the gas?
Ammonia is often produced by reacting nitrogen gas with hydrogen gas. How many liters of ammonia gas can be formed from 23.5 L of hydrogen gas at 93.0°C and a pressure of 34.7 kPa?
Rank the following aqueous solutions in order of increasing boiling point: 0.10 mNa2SO4, 0.10 m SrSO4, 0.25 m sucrose, 0.20 m glucose, 0.15 m NaCl
Calculate the molarity of each of the following solutions(a) 29.0 g of ethanol (C2H5OH) in 545 mL of solution.

What mass of sucrose should be combined with 468 of water to make a solution with an osmotic pressure of 8.75 at 295 ? (Assume the density of the solution to be equal to the density of the solvent.)
A solution is .855% HNO3 by mass. Density of the solution is 1.01 g/mL. Find [H+], [OH-], and pH.
A solution is prepared by dissolving 13.3 g ammonium sulfate in enough water to make 100.0 mL of stock solution. A 11.50 mL sample of this stock solution
A sample of argon gas occupies a volume of 950 mL at 25.0°C. What volume will the gas occupy at 50.0°C if the pressure remains constant?
A mixture of 40 Ml of methyl butyrate (MW-102.1 g/mol,d-0.89 g/mL) and 10 mL butyric acid (MW=88.1 g/mol, d=0.96 g/ML) is distilled.
