Calculate the mass of oxygen (in mg) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the mole fraction of oxygen in air to be 0.21 and the Henry's law constant for oxygen in water at this temperature to be 1.3 × 10-3 M/atm.
Make a FLOW CHART on how a mixture of phenol, benzoic acid, p-nitroaniline and anthracene can be seperated by EXTRACTION.
A solution may contain any of the Group III cations. Treatment of the solutio with CIO- in alkaline medium yields a yellow solution and a colored precipitate.
If the pressure exerted by ozone, {rm{O}}_3, in the stratosphere is 3.0 times 10^{ - 3} {rm{atm}} and the temperature is 251 K, how many ozone molecules are in a liter?
22.05 mL of a sodium hydroxide solution is needed to react completely with 0.5210 g of KHP (molar mass+204.22) What is the concentration of the sodium hydroxide solution
What mass of helium gas is needed to pressurize a 112.0 L tank to 262 atm at 25°C?
A metal-plating waste contains 20mg/L Cu2+, and it is desired to add Ca(OH)2 to precipitate all but 0.5mg/L of the copper. To what concentration in moles per liter must the hydroxide concentration be raised to accomplish this? Ans: 1.6*10^-7 mol/L
After a fatty acid has been desaturated, can it be desaturated a second time immediately thereafter? Why, or why not?
Compute the mass of solute and water needed to prepare the following solutions: 1. 150 g of 1.00 m (NH4)2SO4: (a) from pure solid (NH4)2SO4 (b) from solid (NH4)2SO4 with a purity of 87.2 wt-% 2. 1.50 L of a 20 wt-% Pb(NO3)2 solution whose density ..
what is the mass of the zinc sulfide product. Express your answer with the appropriate units.
When an ionic solid is added into a solvent, you can see that the ionic solid dissociates into its respective cations and anions. The solvent molecules immediately cluster around the ions.
A solution of I2 was standardized with ascorbic acid. Using a .1000 g sample of pure ascorbic acid, 25.32 mL of I2 were required to reach the starch end point. A. What is the molarity of the iodine solution? B. What is the titer of the iodine solu..
Calculate the density of xenon gas at 182 oC and 605 torr. Use R = 0.0821 L-atm/mol-K for the value of the gas constant.
