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

The question is incomplete, here is the complete question:

A solution is made by mixing 146. g of methanol and 72. g of acetic acid . Calculate the mole fraction of methanol in this solution. Round your answer to 2 significant digits.

The mole fraction of methanol is 0.79 and that of acetic acid is 0.21

Explanation:

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

     .....(1)

For methanol:

Given mass of methanol = 146. g

Molar mass of methanol = 32 g/mol

Putting values in equation 1, we get:

For acetic acid:

Given mass of acetic acid = 72. g

Molar mass of acetic acid = 60 g/mol

Putting values in equation 1, we get:

Mole fraction of a substance is given by:

For methanol:

For methanol:

Hence, the mole fraction of methanol is 0.79 and that of acetic acid is 0.21

Electrical charges of ionic bonds

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
