If 18.7 ml of 0.01500 maqueous hcl is required to titrate 15.00 ml of an aqueous solution of naoh to
the equivalence point, what is the molarity of the naoh solution?

Name the element in group 17, period 2. (periodic table)

What substance has a mass of 9.5g and volume of 2.1cm^3

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.
