The molar mass of maltose solution has to be determined. Concept introduction: Colligative properties: Properties of solutions which having influence on the concentration of the solute in it. Colligative properties are, Decrease in the vapor pressure Increase in the boiling point Decline in the freezing point Osmotic pressure Change in freezing point is calculated by using the equation, Δ T f p = K f p m s o l u t e where, K f p is the molal freezing point depression constant. Osmotic pressure: The pressure created by the column of solution for the system at equilibrium is a measure of the osmotic pressure. π = i c R T where, c is the molar concentration i is the van’t Hoff factor The number of moles of any substance can be determined using the equation Number of mole = Given mass of the substance Molar mass Density is calculated by the equation, Density = mass volume Molarity (M): Molarity is number of moles of the solute present in the one liter of the solution. Molarity (M) = Number of moles of solute 1 liter of solution

Solutions

Chapter 13, Problem 78GQ

(a)

Interpretation Introduction

Interpretation: The molar mass of maltose solution has to be determined.

Concept introduction:

Colligative properties: Properties of solutions which having influence on the concentration of the solute in it. Colligative properties are,

  • Decrease in the vapor pressure
  • Increase in the boiling point
  • Decline in the freezing point
  • Osmotic pressure

Change in freezing point is calculated by using the equation,

  ΔTfp=Kfpmsolute

  where,

  Kfp is the molal freezing point depression constant.

Osmotic pressure: The pressure created by the column of solution for the system at equilibrium is a measure of the osmotic pressure.

  π=icRT

  where,

  c is the molar concentration

  i is the van’t Hoff factor

The number of moles of any substance can be determined using the equation

  Numberofmole=GivenmassofthesubstanceMolarmass

Density is calculated by the equation,

  Density=massvolume

Molarity (M): Molarity is number of moles of the solute present in the one liter of the solution.

  Molarity (M) =Numberofmolesofsolute1literofsolution
