A 89 L sample of dry air is cooled from 134°C to -18°C while the pressure is maintained at 2.85 atm. What is the final volume?
A mixture of MgCO3 and MgCO3·3H2O has a mass of 3.057 g. After heating to drive off all the water the mass is 2.790 g. What is the mass percent of MgCO3·3H2O in the mixture.
How much heat is required to warm 227 g of ice from -45.5°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C.
In the neutralization reaction between sulfuric acid and potassium hydroxide, how much potassium sulfate can be produced if you have 150.0g of sulfuric acid to begin with.
Why is sodium chloride added to the tea solution before extracting with ethyl acetate? 4 grams of calcium carbonate was added to 90 ml's of water in a flask
A solid mixture contains MgCl2 and NaCl. When 0.5000 g of this solid is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25°C
Calculate both the molar and molal concentration of water (H2O) in a solution of pure water when the water is at 10C and 30C. Use an accurate molecular weight for water
What mass of sucrose should be combined with 467 g of water to make a solution with an osmotic pressure of 8.30 atm at 300 K? (Assume the density of the solution to be equal to the density of the solvent.)
Calculate the molarity and mole fraction of a 1.43 m solution of acetone (CH3COCH3) dissolved in ethanol (C2H5OH). (Density of acetone = 0.788 g/cm3; density of ethanol = 0.789 g/cm3.)
