Wjhat is the density of a substance of mass 100 g and volume `10 cm^(3)`

Text Solution

AI Generated Solution

The correct Answer is:
To find the density of a substance, we can use the formula: \[ \text{Density} (\rho) = \frac{\text{Mass} (m)}{\text{Volume} (V)} \] Given: - Mass of the substance, \( m = 100 \, \text{g} \) - Volume of the substance, \( V = 10 \, \text{cm}^3 \) Now, we can substitute the values into the formula: \[ \rho = \frac{100 \, \text{g}}{10 \, \text{cm}^3} \] Calculating the right-hand side: \[ \rho = 10 \, \text{g/cm}^3 \] Thus, the density of the substance is \( 10 \, \text{g/cm}^3 \).
