Let's say that you were asked to find the molecular formula for a compound given its
empirical formula, CH20, and the compound's
molar mass.
The first step in solving such a problem is to
calculate the molar mass for the empirical
formula. What is the molar mass of CH20?
(C=12.01 amu, H=1.008 amu, O=16.00 amu)
[?] g/mol CH20

Give the orbital configuration of the phosphorus (p) atom.

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

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.
