1 atm = 760mmHg
754.3 mmHg / 760 mmHg * 1atm = 0.99 atm
760 mmHg = 101.3 KPa
754.3 mmHg/ 760mmHg *101.3 KPa = 100.54 KPa
Hope this helps!

The height of a column of mercury in barometer is 754.3mm. The atmospheric pressure is 96.09 kPa.
What is Barometer ?
Barometer is used to determine the atmospheric pressure.
How to find the atmospheric pressure ?
To find the atmospheric pressure use the formula
P = [tex]\rho[/tex]gh
where
h is height of mercury column,
g is gravitational constant
[tex]\rho[/tex] density of mercury.
We know that
1 N/m² = 1 Pascal and
1 Pascal = [tex]10^{-3}[/tex] kPa.
Put the value in above formula we get
[tex]P_{atm} = \rho gh[/tex]
= 13 × 10³ kg/m³ × 9.8 m/sec² × 0.7543 m
= 96.09 × 10³ N/m²
= 96. 09 × 10³ Pascal
= 96.09 × 10³ × [tex]10^{-3}[/tex] kPa
= 96.09 kPa
Thus, from above conclusion we can say that The height of a column of mercury in barometer is 754.3mm. The atmospheric pressure is 96.09 kPa.
