Question

a substance having a density of 8.4 g/cm3has a mass of 210g. What is its volume?

Answer 1

• Density=8.4g/cm^3
• Mass=210g

We know

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf\longmapsto Volume=\dfrac{Mass}{Density}$

$\\ \sf\longmapsto Volume=\dfrac{210}{8.4}$

$\\ \sf\longmapsto Volume=2.5cm^3$
