A piece of stone of mass 113 g sinks to the bottom in water contained in a measuring cylinder and water level in cylinder rises from 30 ml to 40 ml. Calculate R.D. of stone.

Explanation

To solve the problem of finding the relative density (R.D.) of the stone, we can follow these steps:

### Step 1: Identify the given data
- Mass of the stone = 113 g
- Initial water level in the measuring cylinder = 30 ml
- Final water level in the measuring cylinder = 40 ml

### Step 2: Calculate the volume of the stone
