Question:
Calculate the molarity, {eq}\displaystyle \text{ M, of KCl when 4.59 g KCl } {/eq} are dissolved in {eq}\displaystyle 1.50 \times 10^3 mL {/eq} of solution. Enter your answer in scientific notation.
{eq}\displaystyle \boxed{\space} \times 10 \text{ M KCl } {/eq}
Molarity:
Dissolving a substance as a solute in another substance acting as a solvent, creates a homogeneous mixture of these components that is termed a solution. In a given solution volume in liters there is a certain mass of each solute dissolved, which is related to a molar quantity through the solute's molar mass. The molarity of the solute is defined in terms of these molar and volume values, so it has units of "mol/L" (abbreviated "M").
