MOLARITY GCHEM I LAB CONCEPT PROBLEMS 1. If 5.505 moles of NaOH is dissolved in 2.13 liters of H 2 O, what is the molarity of the solution ? 2. You have 10.00 moles of CuSO 4 and wish to make 4.3 M CuSO 4 solution. What will be final volume of solution ? 3) How many moles of NaCl will be required to make 335.0 mL of 5.0 M NaCl solution ? 4) What is molarity of a HCl solution if the solution contains 1.865 grams HCl / 150.0 mL of solution? 1) What is molarity of the solution that contains 145.0 grams of NaOH dissolved in 6.00 liters of water ? 2) How many liters of 4.22 M NaOH solution will you make if you add water to 380.5 grams of NaOH ? 3) How many grams of CuSO 4 ( MM =159.62 grs/mole) must be added to 5.15 liters H 2 O to make 0.202M solution ? 4) You add 115.0 grams of a compound to 810.0 mLs of H 2 O to make a 5.70 M solution. What is molar mass of compound ? Molarity = Moles of Solute / Volume of Solvent (L) Molarity = Grams of Solute / Molar Mass of Solute Volume of Solvent (L)
