<span>The pH is given by the Henderson - Hasselbalch equation:
pH = pKa + log([A-]/[HA])
pH = -log(</span><span>1.3 x 10^-5) + log(0.50/0.40)
pH = 4.98
The answer to this question is 4.98.

<u>Answer:</u> The volume of bone for given sample is 
<u>Explanation:</u>
To calculate volume of a substance, we use the equation:

Density of bone =
(Conversion factor: 1 g = 1000 mg)
Mass of bone = 25 g
Putting values in above equation, we get:

Hence, the volume of bone for given sample is
