In your reactions, you diluted the provided stock concentration of ADH for your alcohol. Calculate the actual ADH concentration
Fittoniya [83]

Answer:

10^-3 M.

Explanation:

The chemical compound known as the ADH is a hormone with chemical formula of C46H65N15O12S2, and the

Molar mass of 1084.24 g mol^−1. The chemical compound that is ADH is very important in human body as it helps in regulation of blood and also the regulation of water in human body.

STEP ONE: Convert the value of mg/ml to g/l. That is;

35mg/ml = 35g/l.

STEP TWO: Determine the number of moles.

The number of moles = 35 /35000 = 10^-3 moles.

STEP THREE: Determine the concentration.

Number of moles = concentration × volume.

10^-3 = concentration × 1.

The concentration of ADH = 10^-3 M.

While performing the assays for the LDH kinetics experiment, you will pipet 25ul of 250 ug/ml LDH into 975 ul of assay buffer (T
ArbitrLikvidat [17]

Answer:

6.25 μg/mL

Explanation:

When a dilution is made, the mass of the solute is conserved (Lavoiser's law), so the mass pipetted will be the mass in the assay. The mass is the concentration (C) multiplied by the volume (V). If the pipet solution is called 1, and the assay 2:

m1 = m2

C1*V1 = C2*V2

C1 = 250 μg/mL

V1 = 25 μL

V2 = 975 μL + 25 μL = 1000 μL (is the final volume of the assay after the addition of LDH)

250*25 = C2*1000

C2 = 6.25 μg/mL

Explain why an insoluble compound added to water is considered a nonelectrolyte.
DaniilM [7]

Explanation:

A non-electrolyte is defined as a solution which does not contain any ions and hence, it is unable to conduct electricity.

For example, when a non-polar substance like CCl_{4} is dissolved in water then it will not dissociate into ions.  

As electricity is the flow of ions or electrons. So, a non-electrolyte solution is not able to conduct electricity.

Similarly, a compound that is insoluble in water will not dissociate into ions. Hence, this type of solution will not be able to conduct electricity.
