What is the molarity of a solution that contains 17 g of #NH_3# in .50 L of solution? Chemistry Solutions Molarity 1 Answer Manish Bhardwaj Apr 17, 2016 1 molar Explanation: Molarity (M) = number of moles of solute (n) / volume of solution ( L) number of moles of solute , n = mass of solute (g) / molar mass ( g/mol) n = (17 g / 34 g/mol) n = 1/2 = 0.5 mol M = 0.5 mol / 0.50 L M = 1 mol / L Answer link Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400...
