Question
What is the molar concentration of a solution of NaOH that has a m/v% of 27.2%?
Solution
To calculate the molar concentration of a solution, we need to know the molarity formula which is:
Molarity (M) = moles of solute / liters of solution
Given that the mass/volume percent (m/v%) is 27.2%, this means that there are 27.2 g of NaOH in 100 mL of solution.
First, we need to convert the mass of NaOH to moles. The molar mass of NaOH is approximately 40 g/mol. So,
Moles of NaOH = 27.2 g / 40 g/mol = 0.68 moles
Next, we need to convert the volume of the solution to liters.
Volume of solution = 100 mL = 0.1 L
Now we can calculate the molarity:
Molarity (M) = 0.68 moles / 0.1 L = 6.8 M
So, the molar concentration of the NaOH solution is 6.8 M.
