(a)

Interpretation Introduction

Interpretation:

The molality and the molarity of ethanol (C2H5OH) solution and also the volume of solution containing 0.250mole ethanol (C2H5OH) has to be determined.

Concept introduction:

Molality (m): Molality is the number of moles of solute present in one kilogram of solvent.

Molality (m) =Numberofmolesofsolute1kgofsolvent

(b)

Interpretation Introduction

Interpretation:

The molality and the molarity of ethanol (C2H5OH) solution and also the volume of solution containing 0.250mole ethanol (C2H5OH) has to be determined.

Concept introduction:

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

Molarity (M) =Numberofmolesofsolute1literofsolution

(c)
