Final answer:
To convert from molality to molarity, we need to take into account the density of the solution.
Step-by-step explanation:
To find the molar concentration of the solution, we need to convert the given molal concentration to molarity. The molality of a solution is defined as the number of moles of solute per kilogram of solvent, while molarity is defined as the number of moles of solute per liter of solution.
To convert from molality to molarity, we need to take into account the density of the solution. In this case, the density is 1.249 g/mL, which means that 1 mL of the solution has a mass of 1.249 g.
We can use the following formula to relate molality and molarity: Molarity = molality / (1 - density x molality).
Plugging in the given values, we get: Molarity = 4.8 m / (1 - 1.249 g/mL x 4.8 m).
Simplifying the equation gives us: Molarity = 4.8 m / (1 - 5.9952 g/mL).
Therefore, the molar concentration of the solution is 4.8 m / (1 - 5.9952 g/mL).
