Step 1

The given weight of diazepam is 10 mg.

It is known that 1 mg = 10-3 g.

Therefore, 10 mg = 10×10-3 g

The molar mass of diazepam is 284.7 g/mol.

Therefore, the number of moles of diazepam is,

Step 2

The given molarity is 20.0 mM.

It is known that 1 mM = 10-3 M.

Therefore, 20 mM = 20×10-3 M.

The mathematical expression of molarity is,

Step 3

Put the value of molarity and moles in the a...
