<u>Answer:</u> The volume of bone for given sample is $30.49cm^3$

<u>Explanation:</u>

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 $30.49cm^3$

Hitman42 [59]

The reaction would produce bubbles of gas.

We can prepare 3-5 test tubes of acid with increasing concentrations. Then, we add antacid tablets to each and note the time taken for the tablet to dissolve and stop producing bubbles. The lesser the time taken, the greater the rate of reaction.
