Question

This patient has a bone density of 820mg/cm3. What is the volume of a 25g sample?

Answer 1

Answer: The volume of bone for given sample is $30.49cm^3$

Explanation:

To calculate volume of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of bone = $820mg/cm^3=0.82g/cm^3$      (Conversion factor:  1 g = 1000 mg)

Mass of bone = 25 g

Putting values in above equation, we get:

$0.82g/cm^3=\frac{25g}{\text{Volume of bone}}\\\\\text{Volume of bone}=30.49cm^3$

Hence, the volume of bone for given sample is $30.49cm^3$
