According to molar concentration, the final concentrations of the following aqueous solutions after each has been diluted to a final volume of 25.0 mL are 0.018 M,0.2736 M,1.16 M respectively.
<h3>What is molar concentration?</h3>
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.
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.
In the given problem, final concentrations are calculated by the formula, M₁V₁=M₂V₂
Substitution in case of A) gives M₂=0.453×1/25=0.018 M.
Substitution in case of B) gives M₂=2×3.42/25=0.2736 M.
Substitution in case of C) gives M₂=5.80×5/25=1.16 M.
Thus, the final concentrations are 0.018 M,0.2736 M and 1.16 M respectively.
