Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. suppose that the volume of a particular sample of cl2 gas is 8.80 l at 895 torr and 25 ∘c. at what pressure will the volume equal 5.90 l if the temperature is 56 ∘c?

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.

Can someone me with 6 to 10 plz this is for masteries test.
