Express the terms representing the following formulae .
(i)`"No. of moles of solute"/"Volume of solution in litres"=(W)`
(ii)`"No. of moles of solute"/"Mass of solvent in kg"=(X)`
(iii)`"No. of moles of component"/"Moles in the solution"=(Y)`
(iv)`"Mass of component"/"Mass of solution"=(Z)`

Options

A. Molality ,Molarity,Mass fraction,Mole fracton
B. Molarity, Molality , Mass fraction ,Mole fraction
C. Molarity,Molality , Mole fraction,Mass fraction
D. Molality , Molarity ,Mole fraction,Mass fraction

Answer

C

Explanation

`M =(" No. of moles of solute ")/("Volume of solution in L ")`
`m= ( n_(B))/( "Mass of solvent in kg") , x = ( n_(B))/( n_(A) +n_(B))`
Mass fraction `= ( W_(B))/( W_(A) +W_(B))`
