Answer:
The atmospheric pressure from a mercury barometer equals to 99.992 kilopascals.
Explanation:
760 milimeters of mercury column is equal to 101.325 kilopascals. The atmospheric pressure is found by simple rule of three:
[tex]p_{atm} = \frac{750\,mm\,Hg\times 101.325\,kPa}{760\,mm\,Hg}[/tex]
[tex]p_{atm} = 99.992\,kPa[/tex]
The atmospheric pressure from a mercury barometer equals to 99.992 kilopascals.
