The mole fraction of `CH_(3)OH` in an aqueous solution is 0.02 and its density is `0.994 g cm^(-3)`. Determine its molarity and molality.

Explanation

To solve the problem of determining the molarity and molality of an aqueous solution of methanol (CH₃OH) given its mole fraction and density, we can follow these steps:

### Step 1: Define the Variables
Let:
- \( X \) = number of moles of CH₃OH
- \( Y \) = number of moles of water (H₂O)

Given:
