what would be the resulting molarity of a solution made by dissolving 21.9 grams of KCl in enough water to make an 869-milliliter solution? show all of the work needed to solve this problem.

Question

Vocaloid · Answer

molarity = moles solute/L of solvent

in this case, your solute is KCl and your solvent is water

you have KCl in grams, so divide by the molar mass of KCl to get grams
you have mL of water, so divide mL by 1000 to get L

after that, simply divide moles KCL/L of water

please let me know if anything was unclear, or you simply want to check your answer
