C) 12.8 M: 42) A solution is prepared by dissolving 98.6 g of NaCl in enough water to form 875 mL of solution. Calculate the mass % of the solution if the density of the solution is 1.06 g/mL.
• Mass of Solution = 100 g ; Mass of H 2 SO 4 = 15g . Mass of water (solvent) = 100 – 15 = 85 g . Mol. mass of H 2 SO 4 = 98 ∴ 15 g H 2 SO 4 = 15 / 98 = 0.153 moles . Thus 85 g of the solvent contain 0.153 moles 1000 g of the solvent contain . Hence the molality of H 2 SO 4 Solution = 1.8 m . Calculation of molarity: 15 g of H 2 SO 4 = 0.153 ...
To calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements:

• solutions are those that contain two or more chemical compounds in addition to the solvent. To make a complex solution with solid solutes, you treat each solute individually when determining the mass of that compound to add to the solution. For example, to make a five liter solution of 50 millimolar NaCl and ten millimolar tris-HCl, you
• Anyone who has made instant coffee or lemonade knows that too much powder gives a strongly flavored, highly concentrated drink, whereas too little results in a dilute solution that may be hard to To find the number of moles of CoCl2·2H2O, divide the mass of the compound by its molar mass.

• concentration term “molarity”. To calculate the molarity of a solution, simply divide the number of moles of substance it contains (solute) by the volume of the solution, in liters. Using our NaCl example, a 1 molar (M) solution of NaCl contains: a 0.5 molar solution would contain 0.5 moles, and so forth.
• mass percent = g of solute x 100 g of solute + g of solvent amount in g of solute in 100 g of solution. mass percent = g of solute a 100 g of solution Mass Percent * The calculation of mass percent (% m/m) requires the grams of solute (g NaCl) and grams of solution (g NaCl solution).
