Question

A solution of two components containing  moles of 1st component and  moles of 2nd component. ,  are molecular weights. If  is density in g/mL,  is molarity and  is mole fraction of 2nd component, then  can be expressed as:

Strategy:
 Molarity () is moles of solute () per Litre of solution. Express the total solution volume in terms of mole fractions (), molecular weights (), and density ().

Step 1: Relate mass and volume to mole fraction
Total moles . Basis of  mole ():
- Mass of solution .
- Volume of solution (in mL) .
- Volume in Litres .

Step 2: Formulate Molarity
