Question

if an object has a weight of 30 kg and volume of 10 litres what is the density​

Answer 1

Given

Weight = 30kg

we know that

weight = mass *gravity

mass = 30/10= 3kg

Volume = 10L

so

density = 3/10= 0.3

Answer 2

Answer:

density = mass/volume

so density = mass

mass= ?

mass = 30/10 (gravity of earth)

so mass= 3kg

and therefore density = 3/10

i.e 0.3ml/kg
