Question

an iron ball having a mass28 g is added to a cylinder containing 45 ml of water the water rises at 49 ml what is the density of iron in cgs and si unit

Answer 1

• Mass=28g
• Volume=49-45=4mL

We know

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

$\\ \sf\longmapsto Density=\dfrac{28}{4}$

$\\ \sf\longmapsto Density=7g/mL$
