Tutorial 4 SOLUTION STOICHIOMETRY - EIU
T-27 Tutorial 4 SOLUTION STOICHIOMETRYS olution STOICHIOMETRY calculations involve chemical reactions taking place in the various methods of expressing SOLUTION concentration the most convenient for generallaboratory use is molarity, which is defined: Moles of solute nsoluteMolarity = or M = Liters of SOLUTION LsolnChemical reactions are written in terms of moles of reactants and products; this molarityconcentration unit relates moles of solute to volume of SOLUTION . Thus, easily measured solutionvolumes provide a simple method of measuring moles of : What is the molarity of a SOLUTION made by dissolving g of potassium chloridein enough water to make mL of SOLUTION ?
g) 0.655 g of sodium carbonate in 100.0 mL of solution. h) 2.50 x 10–6 kg of potassium phosphate in 500.0 mL of solution. 2) What mass of solute is contained in 25.00 mL of a 0.500 M sodium hydroxide solution? 3) What mass of solute is needed to prepare 250.0 mL of a 1.50 M potassium nitrate solution?
