Which would be the best way to represent the concentration of a 1. 75 M K2CrO4 solution? 1. 75% K2CrO4 [K2CrO4] (K2CrO4) K2CrO4,
tekilochka [14]

The amount of the solute present in the given solution is called the concentration. The best way to represent the concentration of the solution is \rm [K_{2}CrO_{4}].

<h3>What is molar concentration?</h3>

Molar concentration is the molarity of the solution that is the measure of the concentration of the solute dissolved in the solution.

The formula for calculating molar concentration is given as,

\rm Molarity = \dfrac{\text{moles of solute}}{\text{Solution in L}}

The concentration of any substance is represented in the square bracket like \rm [X] or  \rm [K_{2}CrO_{4}].

Therefore, option B. \rm [K_{2}CrO_{4}] is the representation of the concentration.
