What is the pH of an aqueous solution of 3.99×10-2 M nitric acid?
pH =
2NOBr(g) 2NO(g) + Br2(g)
If 0.364 moles of NOBr(g), 0.448 moles of NO, and 0.543 moles of Br2 are at equilibrium in a 19.1 L container at 464 K, the value of the equilibrium constant, Kc, is .
The vapor pressure of benzene is 73.03 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in benzene is TNT.
Calculate the vapor pressure of the solution at 25 °C when 8.249 grams of TNT, C7H5N3O6 (227.1 g/mol), are dissolved in 236.0 grams of benzene.
benzene = C6H6 = 78.12 g/mol.
VP(solution) = mm Hg
