Calculate the vapor pressure of a solution containing 29.4 g of glycerin (C3H8O3) in 120 mL of water at 30.0 C. The vapor pressure of pure water at this temperature is 31.8 torr. Assume that glycerin is not volatile and dissolves molecularly (i.e., it is not ionic) and use a density of 1.00 g/mL for the water.
For CH2CBr2, which geometric isomers do you suppose is energetically most stable; containing less repulsion energy: cis or trans
Calculate the vapor pressure lowering of a solution of 2.40 g of aspirin (molecular weight = 180.15 g/mol) in 55.0 g of methanol (CH3OH) at 21.2°C
A solution is made by mixing 45.0 mL of ethanol, C2H6O, and 55.0 mL of water. Assuming ideal behavior, what is the vapor pressure of the solution at 20 °C
Without a reference sample of a pure compound, can melting point alone be used to unambiguously assignt the correct chemical structure
The cylinder diameter is 2 inches and the depth of the water in the cylinder is 4 inches. Determine the concentration of salt in solution, showing your answer in the units specified.
At which pressure would nitrogen gas be most soluble. 1.0 atm, 1.5 atm , 2.0 atm or d.25atm
In the interest of conserving fuel and funds, you keep the thermostat of your home/apartment at 15°C (59°F) throughout the winter months. You are able to tolerate this condition if the outside (ambient) air temperature exceeds -10°C (14°F) but fee..
Assume constant temperature and the reaction goes to completion, producing as much nitrogen dioxide (NO2) as possible according to the following equation. What is the total pressure, in atm, in the system after the reaction?
Calculate the pH at the equivalence point in a 0.10 M acetic acid/0.10 M sodium hydroxide titration when 27.4 mL of NaOH was used in titration.
The vapor pressure of a volatile liquid can be determined by slowly bubbling a known volume of gas through it at a known temperature and pressure.
A gaseous mixture containing 0.200 mol fraction of carbon tetrachloride (CCl4) and 0.800 mol fraction of dry air is initially at 68.0°C and 1169 mmHg. 1- If this mixture is cooled at a constant pressure, at what temperature does the CCl4 first sta..
