Question

A sample of iron has a mass of 46.8 grams and a volume of 6 cm3. what is the density of iron?

Answer 1

7.8 g/cm3 because Mass/Volume=Density

Answer 2

Answer:

$7.8 g/cm^{3}$

Explanation:

Density, denoted by the greek symbol rho (ρ),  is the mass per unit of volume and it is also called specific mass. For a pure substance, density has the same value as the mass concentration.

The equation to calculate the density is as follows:

ρ= $\frac{m}{v} =\frac{mass}{volume}$

Replacing the mass and volume given in the statement, we optain:

ρ=$\frac{46.8 g}{6cm^{3} } =7.8\frac{g}{cm^{3} }$

Obtaining a similar value to that of the theoretical density of iron, wich is $7.874 g/cm^{3}$
