A2.75 kg sample of a substance occupies a volume of 250.0 cm3. find its density in g/cm3.

dsf

Explanation:

It is known that density is the amount of mass present in per liter of a substance.

Mathematically,    Density =

It is given that mass is 2.75 kg or 2750 g (as 1 kg = 1000 g) and volume is 250 .  

Therefore, calculate the density of substance as follows.

                    Density =

                                 =

                                 = 11

Thus, we can conclude that density of given substance is 11 .

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
