Question

Which is the solute and which is the solvent in a solution of 50g of water and 50g of ethanol? Use an equation to prove your point.

Answer 1

solute- the substance which is present in less quantity
solvent- the substance which is present in more quantity

if no. of mole is more than it means molecule will be also more because

no. of molecules=mole*6.0123*10^(23)

hence find the mole in both cases

and

mole=given mass / molecular mass

solute are those having less mole than solvent

ethanol, no. of mole=given mass / molecular mass=50/46.06844=1.086

water no of mole=50/18=2.77

hence water is solvent while ethanol is solute
