If the mole fraction of acetone in water is 0.2 then the mass percenta

1.	If the mole fraction of acetone in water is 0.2 then the mass percentage (w/w) of acetone in the solution will be (Molar mass of acetone = 58 g
Answer» ANSWER: Mole fraction of solute= Total number of moles of all the solvent Moles of solute X_{A}= \frac{mol A}{mol A + mol B}X A = molA+molB molA And X_{B}= \frac{mol B}{mol A + mol B}X B = molA+molB molB Note: 1. In the given mixture, sum of all the mole fractions is equal to one. XA + XB = 1 2. The multiplication of the mole fraction by 100 GIVES the mole percentage. 3. Mole fraction is a unitless and dimensionless expression Explanation: HOPE it helps you please mark me as a brainlist!

Answer»

Mole fraction of solute=

Total number of moles of all the solvent

Moles of solute

X_{A}= \frac{mol A}{mol A + mol B}X

molA+molB

molA

And

X_{B}= \frac{mol B}{mol A + mol B}X

molA+molB

molB

Note:

1. In the given mixture, sum of all the mole fractions is equal to one.

XA + XB = 1

2. The multiplication of the mole fraction by 100 GIVES the mole percentage.

3. Mole fraction is a unitless and dimensionless expression
