Question

Oceanographers often express the density of sea water in units of kilograms per cubic meter. If the density of sea water is 1.025 g/cm3 at 15ºC, what is its density in kilograms per cubic meter?

Answer 1

Answer: The density in kilograms per cubic meter is 1025

Step-by-step explanation:

Density is defined as mass contained per unit volume.

Given : Density of sea water =
`1.025g/cm^3`

Conversion :
`1.025g/cm^3=?kg/m^3`

As 1 g = 0.001 kg

Thus 1.025 g =
`(0.001)/(1)* 1.025=0.001025kg`

Also
`1cm^3=10^(-6)m^3`

Thus
`1.025g/cm^3=(0.001025)/(10^(-6)kg/m^3)=1025kg/m^3`

Thus density in kilograms per cubic meter is 1025
