A piece of iron has a volume of `25 cm^3` and mass 195 g. Find the density of iron in `kg m^(-3)`

Explanation

To find the density of iron given its mass and volume, we can follow these steps:

### Step 1: Convert mass from grams to kilograms
The mass of the iron piece is given as 195 grams. To convert this to kilograms, we use the conversion factor that 1 kg = 1000 g.

\[ \text{Mass in kg} = \frac{195 \text{ g}}{1000} = 0.195 \text{ kg} \]
