What volume, in liters, of a 2.00 M KCl solution contains 2.5 kg of KCl?

Molar mass of KCl = 74.55 g/mol

Asked by svee123

Answer (2)

According to the molar concentration ,** volume **in liters of 2 M KCl solution is 16.76 L.
What is molar concentration?
Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to** solute concentration** in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to** thermal expansion**. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.
Volume required is obtained by molarity formula as, 2×74.55/2500=1/V=0.05964
∴V=1/0.05964=16.67 L.
Thus, 16.67 L of 2 M KCl solution contains 2.5 kg of KCl.

To obtain 2.5 kg of KCl in a 2.00 M solution, you need approximately 16.79 liters of the solution. This is calculated by converting the mass of KCl to moles and using the molarity formula to find the volume. The molar mass of KCl is needed for the conversion from grams to moles.
