What is the concentration of a solution if 65 g of sugar is dissolved into 200 ml of water? the concentration in g/L 325 while in molarity is 0.6398(M).

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

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.
