Atomic mass of mercury is 200 and density is 13.6 g/L . How many moles of metal are present in one litre ?

Explanation

To solve the problem of how many moles of mercury are present in one liter, we will follow these steps:

### Step 1: Understand the given data
- Atomic mass of mercury (Hg) = 200 g/mol
- Density of mercury = 13.6 g/cm³ (Note: 1 L = 1000 cm³)

### Step 2: Calculate the mass of mercury in 1 liter
Using the formula for density:
