If a cylinder of NO has a volume of 20.00L and a pressure of 26.98 atm at 20 degrees Celcius, what is the mole fraction of NO knowing that there are 21.55moles of Nitrogen?
The mole fraction is:_____________________.
Calculate the approximate molarity of this solution from the volume, percent composition, and density.
What is the approximate ratio of the molar concentrations of CO_2(aq) in the soda before it is opened to that in the soda after it has been opened and reached equilibrium with the surrounding atmosphere
Indicators can be used to estimate the pH value of soultions. To determine the pH of a 0.01M weak acid (HX), a few drops of three different indicators are added to separate portions of HX. The resulting colors of the HX solution are below.
The reaction, seen below, is carried out in a constant-volume flask. Initially only dimethyl ether is present and the pressure is 0.350 atm. What is the pressure of the system after 8.0 minutes? Assume ideal behavior.
A multiple series dilution was performed. The sample was diluted 1/5, 1/2, 1/4, 1/2. What is the final dilution
