Correct option is C
Correct Answer: (c)
Explanation
The
analytical balance, used for highly precise measurement of mass in laboratories, is associated with
Antoine Lavoisier, who emphasized accurate quantitative measurements in chemistry.
Lavoisier extensively used the analytical balance in his experiments and demonstrated that
mass is conserved during a chemical reaction, leading to the
Law of Conservation of Mass.
Hence, the correct answer is
Option (c}: Lavoisier.
Additional Information
•
Antoine Lavoisier (1743–1794} is known as the
"Father of Modern Chemistry."
• His major contributions include:
· Law of Conservation of Mass
· Naming oxygen and hydrogen
· Explaining combustion through the oxygen theory
· Promoting quantitative chemistry using precise measurements
• Analytical balances can measure mass with an accuracy of
0.0001 g (0.1 mg} or better.
