Part 4. Molality of the calcium chloride solution Molality is defined as mol solute Calculate the molality of your assigned calcium chloride solution. Assume that the density of kg solvent water is 1g/mL. Questions (SHOW ALL WORK) 1. Calculate the molarity (M) of a solution when 12.80 g of glycerol (CHsOs) is added to 40.70 g of water. The density of the solution is 1,052g/ml Colligative properties like boiling point elevation depend on the number of solute particles in solution....
A salt solution was made by dissolving 17.32 g of NaCl in 400.0 mL of water. Calculate the molality (NOT molarity) of this solution Hint: Molality (m) = moles of solute / Kg of solvent Use 11Na23 and 17Cl35.5
Calculate the molality of a NaCl solution that has a molarity of .0600 M NaCl if the density of the solution is 1.017g/mL.
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...
A solution of NaCl (MW = 58.5 g/mol) in water (MW = 18.0 g/mol) has the molality of 3.01 molal and the density of 1.112 g/mL. Consider mass of solvent 1 Kg A) What is the mass percent of the solute? (B) What is the molarity of the solution? (C)What is the mole fraction of H2O?
Calculate the molarity and molality of a commercial bleach solution that is 8.62% by mass of NaOCl in water and has a density of 1.10 g/mL.

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...
