The cost of table salt (NaCl) and sugar `(C_(12)H_(22)O_(11))` are Rs 20 per kg and Rs 36 per kg respectively. Calculate their cost per mole.

Explanation

To calculate the cost per mole of table salt (NaCl) and sugar (C₁₂H₂₂O₁₁), we will follow these steps:

### Step 1: Calculate the molar mass of NaCl
1. The molar mass of sodium (Na) = 23 g/mol
2. The molar mass of chlorine (Cl) = 35.5 g/mol
3. Therefore, the molar mass of NaCl = 23 + 35.5 = 58.5 g/mol

### Step 2: Determine the cost of NaCl per gram
