Question

A 2.75 kg sample of a substance occupies a volume of 250.0 cm3. Find its density in g/cm3.

Answer 1

Answer:

dsf

Explanation:

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

Mathematically,    Density = $\frac{mass}{volume}$

It is given that mass is 2.75 kg or 2750 g (as 1 kg = 1000 g) and volume is 250 $cm^{3}$.  

Therefore, calculate the density of substance as follows.

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

                                 = $\frac{2750 g}{250 cm^{3}}$

                                 = 11 $g/cm^{3}$

Thus, we can conclude that density of given substance is 11 $g/cm^{3}$ .

Answer 2

Density is 0.011 g/cm3.
