Question

What is the density of water when:

The weight of an empty cylinder was 50 g, 20 mL of water was placed in the graduated cylinder, and the weight of the cylinder and water was 70 g.

Answer 1

Weight of water=70-50=20g

Volume=20ml

$1ml=1g/cm^3$

Therefore $20ml=20g/cm^3$

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

​

$Density=\frac{20g}{20g/cm^3}=1g/cm^3$

$1g/cm^3=1000Kg/M^3$

The density of water=$1000Kg/M^3$
