Calculate the number of moles of NaCl given its mass and molar mass.

Step 1: Calculate the molar mass of sodium chloride (NaCl).
The atomic mass of Na is 23 and Cl is 35.5.

$$\text{Molar mass of NaCl} = 23 + 35.5 = 58.5 \text{ g/mol}$$

Step 2: Calculate the number of moles of NaCl.
The mass of solid salt obtained is $1.95 \text{ g}$.
