5g of Nacl is dissolved in 1000g of water. If the density of the resulting solution is `0.997` g per "cc", calculate the molality, molality, normality and mole fraction of the solute.

Explanation

To solve the problem step by step, we will calculate the molality, molarity, normality, and mole fraction of NaCl in the solution.

### Step 1: Calculate the number of moles of NaCl
To find the number of moles of NaCl, we use the formula:
\[ \text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
Given:
...
