Answer:

The atmospheric pressure from a mercury barometer equals to 99.992 kilopascals.

Step-by-step explanation:

760 milimeters of mercury column is equal to 101.325 kilopascals. The atmospheric pressure is found by simple rule of three:


p_(atm) = (750\,mm\,Hg* 101.325\,kPa)/(760\,mm\,Hg)


p_(atm) = 99.992\,kPa

The atmospheric pressure from a mercury barometer equals to 99.992 kilopascals.
