A water solution of sodium hypochlorite (NaOCl) is used as laundry bleach. The concentration of sodium hypochlorite is 0.75 m. Express this concentration as a mole fraction.
A 690 g of 59% strontium bromide solution is cooled from 60 oC to a certain temperature. Upon addition of around 2 g of strontium bromide, excess solute above saturation started to crystallize. Total recovered crystals is 146.003 g. At what temperature is the solution cooled?
Just because there appears to be a good match between solubility characteristics between solute and solvent doesn’t mean you’ve found a good system. For example, benzyl alcohol appears to have favorable solubility characteristics with fluorenol, but it is a poor choice of solvent. Explain why this might be.
1.0 GRAMS of an electrolyte was dissolved in 29 grams of water, the resulting solution was found to have a molarity of 0.437 mol / L. The freezing point of the solution was determined to be -4.96°C.

Which of the following statement/s is/are true regarding molarity and molality? Thenumber of equivalents of solute per liter of solution must be taken into account when you use these concentration expressions. Molarityis the number of moles of solute per liter of solution, while molality is the number of moles of solute per kilogram of solution. You can convert molarity to molality if you know thedensity of the solvent. Thedenominator must always be in liters (L)when concentrations are expressed in terms of molarity or molality. Select one: a. II only b. II and III only c. II and IV only d. All e. None
