A furnace exhaust stack is instrumented so that a sample of the stack gas can be analyzed for composition. The analysis gives the following volume fractions: 70.0% N2, 20.0% CO2, 8.00% CO, 1.00% Ar, and 1.00% H2O.
a. What is the molecular mass of the stack gas?
b. Calculate the mass fraction of each of the gases.
c. If the measured pressure in the stack is 15.0 psia, what is the partial pressure of the carbon monoxide?
Calculate the pH of the solution that results from each of the following mixtures.160.0 mL of .27 M HF with 220 mL of .32 NaF
