What is the boiling point of a 0.800 molal solution of sugar in water? Kb = 0.512C/m for water. Sugar does not dissociate in solution and pure water boils at 100C.
What volume of H2 could be produced at a temperature of 19 oC and a pressure of 764 torr by the reaction of 2.98 g of aluminum with hydrochloric acid.
Calculate the [H3O+], pH, and the fraction of dissociation (α) in an aqueous 0.140 M NH3 solution. (Hint: You will need the Ka, located in the back of your textbook.)
volumetric flask and this solution becomes quite warm, but after it is permitted to return to room temperature, H 2 O is combined to total 500 mili litres of solution. Compute the pH of the final solution. ?
Glycerol HOCH2CH(OH)CH2OH is a nonvolatile, water-soluble material. its density is 1.25 g/mL. Predict the vapor pressure of a solution of 2.40 x 10^2 mL of glycerol, in 395 mL of water, at the normal boiling point of water.
A refrigeration tank holding 5.00 L of Freon gas (C2Cl2F4) at 25°C and 3.00 atm pressure developed a leak. When the leak was discovered and repaired, the tank had lost 76.0 g of the gas.
Drag the flask and drop it on the lower half of the burette to connect them. Open the Data window and click on the flask. Click the Pushpin icon in the blue bar of the Data window to lock its display to the flask's contents.
