The relative density of lead is 11.3. What is its density in (1) C.G.S system (2) S.I. unit?

Explanation

To find the density of lead in both the C.G.S. system and the S.I. unit given that the relative density of lead is 11.3, we can follow these steps:

### Step 1: Understand Relative Density
Relative density (also known as specific gravity) is defined as the ratio of the density of a substance to the density of water. The formula can be expressed as:
\[ \text{Relative Density} = \frac{\text{Density of Substance}}{\text{Density of Water}} \]
