It is possible to synthesize ammonia (NH3) by chemically combining nitrogen monoxide (or nitric oxide) and hydrogen.
2 NO(g) + 5 H2(g) →→ 2 NH3(g) + 2 H2O(g)
If 5.44 g of nitric oxide is chemically combined with 3.02 grams of hydrogen, how many grams of ammonia can
one expect?
The molar masses (in g/mol) of H, N, and O are 1.008, 14.01, and 16.00, respectively. Enter your answer to the
nearest hundredth. Just enter the number you get for the answer; the units are understood to be grams.

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.
