Calculate the molarity of each of the following solution :
(a) `"30 g of Co "(NO_(3))_(2).6H_(2)O`in 4.3 L of solution
(Atomic mass of cobalt = 58.7)

Explanation

To calculate the molarity of the solution, we will follow these steps:

### Step 1: Calculate the molar mass of Co(NO₃)₂·6H₂O

1. **Find the atomic masses:**
- Cobalt (Co) = 58.7 g/mol
- Nitrogen (N) = 14 g/mol
- Oxygen (O) = 16 g/mol
