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.

Answer:
2 moles
Explanation:
The following were obtained from the question:
Molarity = 0.25 M
Volume = 8L
Mole =?
Molarity is simply defined as the mole of solute per unit litre of solution. It is represented mathematically as:
Molarity = mole of solute/Volume of solution.
With the above equation, we can easily find the number of mole of MgCl2 present in 8 L of 0.25 M MgCl2 solution as follow:
Molarity = mole of solute/Volume of solution.
0.25 = mole of MgCl2 /8
Cross multiply to express in linear form
Mole of MgCl2 = 0.25 x 8
Mole of MgCl2 = 2 moles
Therefore, 2 moles of MgCl2 are present in 8 L of 0.25 M MgCl2 solution
