Asolution is made by mixing of acetic acid and of acetone . calculate the mole fraction of acetic acid in this solution. round your answer to significant digits.

The question is incomplete, here is the complete question:

A solution is made by mixing 103. g of acetone and 137. g of acetic acid. Calculate the mole fraction of acetic acid in this solution. Round your answer to 3 significant digits.

The mole fraction of acetone in the solution is 0.438

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of acetic acid = 137. g

Molar mass of acetic acid = 60 g/mol

Putting values in equation 1, we get:

Given mass of acetone = 103. g

Molar mass of acetone = 58 g/mol

Putting values in equation 1, we get:

To calculate the mole fraction, we use the equation:

Calculating the mole fraction of acetone:

Hence, the mole fraction of acetone in the solution is 0.438

your answer would be a. 12.5 kg
