Solution
To calculate the concentration (molarity) of a solution, you need the amount of solute and the volume of the solution.
Here are the steps:
-
Determine the amount of solute in moles. This can be done by using the molecular weight of the solute and the given weight. The molecular weight of a substance can be found on the periodic table and is measured in grams per mole (g/mol).
-
Measure the volume of the solution. This is usually done in liters (L).
-
Divide the amount of solute (in moles) by the volume of the solution (in liters). The result is the concentration of the solution in moles per liter, which is also known as molarity (M).
So, the correct answer is "the amount of solute and the volume of solution".
