Question

A student observed that a block of mass 100g displaced 500ml of water when dipped in measuring cylinder calculate the density of the block

Answer 1

the formula of density is mass/volume
mass is100g and volume is 500ml
density=100/500=1/5

Answer 2

Answer: Density= 0.2 g/mL

Explanation:

Density of a substance is the ration of mass and volume.

Volume of an irregular substance can be found by dipping it in fixed volume of water and calculating the amount of water displaced.

The mass of block, m= 100 g

Volume of block = amount of water displaced in the cylinder = 500 mL

$Density = \frac{mass}{volume}$

$\Rightarrow Density = \frac{100g}{500mL}=0.2 g/mL$

Hence, the density of the block is 0.2g/mL.
