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

`7.8 g/cm^(3)`

Step-by-step 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=
`(m)/(v) =(mass)/(volume)`

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

ρ=
`(46.8 g)/(6cm^(3) ) =7.8(g)/(cm^(3) )`

Obtaining a similar value to that of the theoretical density of iron, wich is
`7.874 g/cm^(3)`
