An intravenous solution was prepared by add-in 13.252 g of dextrose (C6H12O6) and 0.686 g of sodium chloride to a 250.0 mL volumetric flask and diluting to the calibration mark with water. What is the molarity of each component of the solution

Explanation:

Molarity(M) of a solution is defined as the number of moles of solute(n) present in one liter of solution(V).

The number of moles(n) can be calculated as shown below:

Molar mass of dextrose is 198.17 g/mol

Molar mass of NaCl is 58.5 g/mol.

Volume of the solution =250.0mL=0.250 L

The number of moels of dextrose() is:

The number of moles of NaCl is:

Thus, the molarity of dextrose is:

The molarity of NaCl is:

The molarity of dextrose is 0.268 M.

The molarity of NaCl is 0.0472 M.
