Final answer:
To find the molarity of a solution, divide the number of moles of solute by the volume of the solution in liters.
Step-by-step explanation:
The molarity of a solution is determined by the number of moles of solute present in one liter of solution. To find the molarity, you can use the formula:
Molarity (M) = moles of solute / volume of solution in liters
Firstly, you need to calculate the number of moles by dividing the mass of the solute by its molar mass. Once you have the moles, divide this value by the volume of the solution in liters to obtain the molarity. For example, if you dissolve 32.7 g of NaOH (₀ with a molar mass around 40 g/mol) to make 445 mL (0.445 L) of solution, the molarity would be the moles of NaOH divided by 0.445 L.
