Question: how to calculate the concentration of two mixed solutions?
Answer: For the example, Solution 1 is 0.05 L and Solution 2 is 0.120 L. The final volume = 0.05 L + 0.120L = 0.170 L. Calculate the final molarity of the mixed solution using the equation molarity = moles ÷ liter. For the example, the final molarity is 0.0135 moles ÷ 0.170 liters = 0.079 M.
