25% v/v means 25.0 g isopropyl alcohol in 100 mL solution.
mols C3H8O = grams/molar mass
Convert 100 mL of the solution to grams using density, then M = mols/L soln.
What is the molarity of a 25.0% (v/v) aqueous isopropyl alcohol solution? the density of isopropyl alcohol ( C3H8O, molar mass 60.1g/mol) is 0.786g/ml
