Using the ideal gas law, pV = RT, prove that the volume of one mole of ideal gas is a state function
How much would the beaker and its content weigh if it was completely filled with mercury? The density of mercury is d = 13.5 g/mL ? = g
Calculate the density in kg/m3 using (a) the ideal gas equation of state and (b) the compressibility factor equation of state in conjunction with the law of corresponding states.
Calculate the mass of propylene glycol that must be added to .360 kg of water to reduce the vapor pressure by 2.87 torr at 40 degrees celsius (Ph20 at 40 degrees = 55.3)
Solid ammonium fluoride is slowly added to 125 mL of a magnesium sulfate solution until the concentration of fluoride ion is 0.0476 M. The maximum amount of magnesium ion remaining in solution is
The aqueous solution was subsequently treated with an excess of AgNO3 solution and the AgCl precipitated was collected and weighed. its mass was 2.022 grams of AgCl.
A 1 L solution of 1.5 M acetic acid and 1.5 M sodium acetate has a ph of 4.74. 10 ml of 0.1 M NaOH were added to the solution followed by the addition of 50 ml of 0.02 M HCl.
which caused the CO2 in the sample to precipitate as BaCO3. The excess base was back-titrated to a phenolphthalein end point with 23.6ml of .0108 M HCl. What is the concentration of CO2 in the air in parts per million? use 1.98g/L for the density ..
Assemble the alcohols (have the formula of C4H10) in the order of increasing reactivity with concentrated HCl.
This strontium isoptope is radioactive, with a half-life of 28.1 years. Calculate how long (in years) it will take for 5.63g of the isotope to be reduced to .354g by decay
Determine the pH, percent ionization and all of the equilibrium concentrations for each of the following.
A certain brand of antacid has a dosage that contain 400 mg Mg(OH)2. How many mmoles of HCl can be neutralized by one dose of this antacid?
For the titration of 50.00 mL of 0.0200 M 2-(N-Morpholino)ethanesulfonic acid with 0.09900 M NaOH, calculate how much titrant (mL) is required to reach a pH of 9.29 mL in the receving flask.
