Question

A sample of pure iron has a mass of 5.00 g calculate its volume.

Answer 1

5/7.874 V = m/d
I used the density of iron is 7.874
volume is 0.645

Answer 2

Answer : The volume of a sample of pure iron is, 0.635 ml

Solution : Given,

Mass of pure iron = 5 gram

Density of pure iron = 7.87 g/ml

Formula used :

$\text{Density of pure iron}=\frac{\text{Mass of pure iron}}{\text{Volume of pure iron}}$

Now put all the given values in this formula, we get the volume of pure iron.

$7.87g/ml=\frac{5g}{\text{Volume of pure iron}}$

$\text{Volume of pure iron}=0.635ml$

Therefore, the volume of a sample of pure iron is, 0.635 ml
