Question

A piece of is on has a volume of 25cm3 and mass 195g.find density in g cm-3 and kgm-3

Answer 1

Hola mate! Here Is your answer:

Given:

Mass=195g=0.195kg

Volume=25cm^3=0.000025m^3

Solution:

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

Density in g/cm^3

$= \frac{195}{25} = 7.8$

Density in kg/m^3

$\frac{0.195}{0.000025}$

$\frac{195 \times 1000000}{25 \times 1000}$

$= 195 \times 40$

=780kg/m^3

Hope it helps!
