46 gms of ethyl alcohol is dissolved in 18 gms of water. Calculate the mole fraction of ethyl alcohol. (At. wt of C = 12, 0 = 16, H= 1).

Explanation

To calculate the mole fraction of ethyl alcohol in a solution, we can follow these steps:

### Step 1: Calculate the number of moles of ethyl alcohol (C2H5OH)

The formula for calculating the number of moles is:

\[
\text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}
