Acidity of lactic acid = pKa = 3.85
Ca = 0.13M
Cs = 0.11M
<span>Henderson-Hasselbalch equation:</span>
pH = pKa + log(Cs/Ca)
pH = 3.85 + log(0.11M/0.13M) = 3.85 + log0,846 = 3.85 - 0.073 = <u>3.777</u>
Answer:
Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.Mass is the scalar quantity and weight is a vector quantity. The unit of mass is kg while the unit of weight is N. Mass can't be changed by changing place, weight can be changed by changing the place.
