In the actual experiment 146.2 mL of O2(g) was collected. This is because the O2(g) was collected over water and the atmospheric pressure includes both the pressure of oxygen and water vapor. Use Dalton’s Law of Partial Pressures and Boyle’s Law to correct for the water vapor pressure and determine the volume of dry oxygen.

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
