Answer:
A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.
Answer:- Molarity of the acid solution is 0.045M.
Solution:- The balanced equation for the reaction of given acid and base is:

From the balanced equation, they react in 1:1 mol ratio. So, we could easily solve the problem using the equation:

where,
is the molarity of acid,
is the molarity of base,
is the volume of acid and
is the volume of base.
Let's plug in the given values in the equation:

on rearranging the above equation:

= 0.045M
So, the molarity of the acid solution is 0.045M.
