First, we need to calculate the moles of acetic acid in 7.50 mL of glacial acetic acid.
Mass of acetic acid = volume x density = 7.50 mL x 1.05 g/mL = 7.88 g
Molar mass of acetic acid (HC2H3O2) = 60.05 g/mol
Number of moles = mass / molar mass = 7.88 g / 60.05 g/mol = 0.131 mol
Now, we can calculate the molarity of the solution.
Molarity (M) = moles of solute / liters of solution
Liters of solution = 500.0 mL / 1000 mL/L = 0.500 L
Molarity = 0.131 mol / 0.500 L = 0.262 M
Therefore, the molarity of the solution prepared by dissolving 7.50 mL of glacial acetic acid in sufficient water to give 500.0 mL of solution is 0.262 M.
Pure acetic acid (HC2H3O2) is a liquid and is known as glacial acetic acid. Calculate the molarity of a solution prepared by dissolving 7.50 mL of glacial acetic acid at 25 °C in sufficient water to give 500.0 mL of solution. The density of glacial acetic acid at 25 °C is 1.05 g/mL.
