Calculate the minimum volume of distilled water, in liters, necessary to completely dissolve a 7.5 g sample of AgBr (s) at 298K. The molar mass of AgBr is 188 g mol.
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
The vapor pressure of pure ethyl bromide at this temperature is 400.0 torr. Assuming an ideal solution, what is the molecular mass of the compound?
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..
gas is introduced into an evacuated 3.58 L flask at 65 deg. C, what is the pressure inside the flask
the mass spectrum determined the molecular weight of mehtyl salicylate to be 125.15 g/mol. What is the molecular formula of methyl salicylate?
During the laboratory exercise you will need 100.00mL of a 0.20M Ni^+2 solution and 25.00ml of a 0.10M Co^+2 solution. You will prepare the Ni^+2 solution from solid NiSO4 (X) 6H20 and the Co^+2 solution from solid Co(NO3)2 (X) 6H20
what is the pH of a solution obtained by adding 3.50g of HBr to 435mL of a 0.639M solution of HNO3?
A 3.84-mole sample of a gas is held at a temperature of 297 K and a pressure of 286 atm. Determine the volume of the gas sample.
Wastewater flow in a sewer can be estimated by adding a known amount of tracer such as salt solution and measuring the salt concentration upstream and downstream of the point of addition.
