Item 5 a solution of methanol, ch3oh, in water is prepared by mixing together 128 g of methanol and 108 g of water. the mole fraction of methanol in the solution is closest to

Mole fraction of methanol will be closest to 4.

Explanation:

Given, Mass of methanol = 128 g

Molar mass of methanol = 32.04 g/mol

The formula for the calculation of moles is shown below:

Thus,

Given, Mass of water = 108 g

Molar mass of water = 18.0153 g/mol

The formula for the calculation of moles is shown below:

Thus,

So, according to definition of mole fraction:

Mole fraction of methanol will be closest to 4.
