What is the concentration in g/L of a solution containing 0.5 moles of KCl in 1.

What is the concentration in g/L of a solution containing 0.5 moles of KCl in 1.5 L of solution? (Molar mass of KCl = 74.5 g/mol)

What is the concentration in g/L of a solution containing 0.5 moles of KCl in 1.5 L of solution? (Molar mass of KCl = 74.5 g/mol)

Step 1: Identify the number of moles of KCl in the solution, which is given as 0.5 moles.
Step 2: Find the molar mass of KCl, which is given as 74.5 g/mol.
Step 3: Calculate the mass of KCl using the formula: Mass = moles × molar mass. So, Mass = 0.5 moles × 74.5 g/mol.
Step 4: Perform the multiplication: 0.5 × 74.5 = 37.25 g. This is the mass of KCl in grams.
Step 5: Identify the volume of the solution, which is given as 1.5 L.
Step 6: Calculate the concentration in g/L using the formula: Concentration = mass / volume. So, Concentration = 37.25 g / 1.5 L.
Step 7: Perform the division: 37.25 g ÷ 1.5 L = 24.83 g/L. This is the concentration of the solution.
