Final answer:
To find the molar concentration of a 50 mg KMnO4 solution, convert the mass to moles, and divide by the volume of the solution, resulting in a concentration of 0.632 M.
Step-by-step explanation:
The molar concentration of a solution is found by calculating the number of moles of solute divided by the volume of the solution in liters. To find the molar concentration of a solution containing 50 mg of KMnO4, we first convert the mass of KMnO4 to moles. Given the molar mass of KMnO4 is 158.034 g/mol, 50 mg is 0.050 g. Next, we use the molarity equation:
Molarity (M) = moles of solute / volume of solution (L)
Thus, Molarity = (0.050 g / 158.034 g/mol) / 0.500 L = 0.632 M.
Therefore, the final answer is that the molar concentration of the solution is 0.632 M.
The molar concentration of the solution is 0.632 M. To calculate the molar concentration, we need to convert the mass of KMnO₄ to moles. The molar mass of KMnO₄ is 158.034 g/mol. Therefore, 50 mg of KMnO₄ is equal to 0.050 g.
Using the formula: Molarity (M) = moles of solute / volume of solution (L), we can calculate the molar concentration as follows: Molarity = (0.050 g / 158.034 g/mol) / 0.500 L = 0.632 M.
