Consider a 0.300 M solution of NaOH? Calculate the molality of NaOH. (Assume the density of the solution is the same as the density of pure water.) Assume that you have 1 L of solution: Mass of water = mass of solution – mass of NaOH = 1000 g – (0.300 mol)(40 g/mol) = 1000 g – 12 g = 988 g. Molality = 0.300 mol/0.988 kg = 0.304 m

Calculate the molarity of 34.2 grams of sugar, C12H22O11 in 500.0 mL of solution. What is the molar concentration of 1.0 mol of KCl dissolved in 750.0 mL of solution? Calculate the number of moles of NaOH contained in 250. mL of a 0.05M solution. Calculate the molarity of 29.25 grams of NaCl in 2.0 liters of solution.
Standardization of a NaOH Solution with Potassium Hydrogen ...
NaOH has 1 equivalent per mole so Normality = Molarity. Sufuric acid has 2 equivalents of acid per mole so N = 2eqM = 2eq mol. so 2M=N (see page 487 in the textbook) L
