Answer 2

Calculation of Mass Fraction of Solute in Solution

To find the mass fraction of the solute in the resulting solution, we need to know the initial mass of the solute and the total mass of the resulting solution.

Given: - Initial mass of the solute = 80 g - Mass of the solvent added = 160 g

To calculate the mass fraction of the solute, we can use the formula:

Mass Fraction = (Mass of Solute) / (Mass of Solution)

Let's substitute the given values into the formula:

Mass Fraction = (80 g) / (80 g + 160 g)

Simplifying the equation:

Mass Fraction = 80 g / 240 g

Calculating the value:

Mass Fraction = 1/3

Therefore, the mass fraction of the solute in the resulting solution is 1/3 or approximately 0.333.
