Interpretation : The aqueous solution of methanol in which the mole fraction of methanol is
Concept Introduction : The molality and mole fraction are the two ways to express the percentage of solute to solvent particles. The ratio of a solute's moles to the sum of the moles of solvent and solute in a solution is known as the solute's mole fraction.
The formula of the mole fraction is given as
Here,
Answer to Problem 70A
The aqueous solution of methanol is prepared by mixing
Explanation of Solution
The mole fraction of methanol is
The molar mass of methanol is
The molar mass of water is
The moles of methanol
The formula of the mole fraction of methanol with water as a solvent is given as:
The moles of water are to be found.
To calculate the moles of water, substitute the values in formula (1) as follows:
Further, solve the above equation.
The moles of water are
To calculate the amounts of solute and solvent, multiply the moles by their molar mass.
The amount of
The amount of
