Determine the molality of a solution of benzene dissolved in toluene (methylbenzene) for which the mole fraction of benzene is 0.176. give your answer to 2 decimal places

2.32 m

Explanation:

So, according to definition of mole fraction:

Mole fraction = 0.176

Applying values as:

So,

Also, Molar mass of toluene = 92.14 g/mol

Thus,

The formula for the calculation of moles is shown below:

Also, 1 g = 0.001 kg

So,

Molality is defined as the moles of the solute present in 1 kg of the solvent.

It is represented by 'm'.

Thus,  

Molality of benzene = 2.32 m
