Question

The density of air is 1.28g/litre.Express it in (a)g/cm²(b)kg/m³​

Answer 1

Answer:

Density of air is 1.28g/l

now 1l=1000cm^3

therefore density of air=1.28/1000 g/cm^3

that is=0.0128g/cm^3

also 1g=0.001kg

and 1l=0.001m^3

therefore density of air=1.28kg/m^3

hope it will help you

Answer 2

Answer:

B - kg/m^3

Explanation:

Density of air is 1.28g/l

now 1l= 1000cm^3

therefore density of air=1.28/1000 g/cm^3

that is=0.0128g/cm^3

also 1g=0.001kg and

1l=0.001m ^3

therefore density of air =1.28 kg/m^3
