Calculate the vapor pressure of a solution containing 25.3g of glycerin C3H8O3 in 125mL of water at 30.0C. The vapor pressure of pure water at this temperature is 31.8torr}. Assume that glycerin is not volatile and dissolves molecularly (i.e., it is not ionic) and use a density of 1.00g/mL for the water.
The reaction 2NO(g) + Cl2 (g) -> 2NOCl(g) is carried out in a closed vessel. If the partial pressure of NO is decreasing at the rate of 21 torr/min, what is the rate of change of the total pressure of the vessel?
The annual production of zinc sulfide (ZnS) is 3.5 10^4 tons. Estimate the number of tons of SO2 produced by roasting it to extract zinc metal.
If the density of N2 gas in a rigid flask is 0.243 g/L at 18 °C, what is the pressure of nitrogen in the flask if it is heated to 36 °C
In combustion studies of H2 as an alternative fuel, you find evidence that the hydroxyl radical (HO) is formed in flames by the following reaction
Calculate the number of moles of ions present in 66.8 g of a solution that is 2.11% Fe(NO3)3 by mass.

When a solution of a certain gadolinium salt ie electrolyzed with current of 1.0 A for 2.0 h, 0.025 mol of Gd metal forms. Calculate the charge on the gadolinium ion in the salt
Two solid forms of elemental sulfur (S8) are rhombic and monoclinic, denoted A and B, respectively. For the transformation S8(s,A) --> S8(s,B), dH* = 330 J/mol and dS* = 80 J/mol*K.
the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 55.0 atm, what was the volume of the sample? Assume that the temperature was held constant.
A mixture of gases contains 2.89 g of N2, 5.38 g of H2, and 9.00 g of NH3. If the total pressure of the mixture is 2.24 atm, what is the partial pressure of each component?
