Answer:

the liquid has less height than the mercury

      h_{ liquid} = [tex]\frac{\rho_{Hg} }{\rho_{liqid}} \ h_{Hg}[/tex]

Explanation:

The pressure as a function of the height is given by

        P = ρ g h

where ρ is the density of the liquid, g the acceleration of gravity and h the height reached by the column of the liquid

In that case they say that the pressure is the standard one that is P = 1.01 10⁵ Pa = 760 mmHg

The first way to give the pressure is in SI units and the second way is the height that the mercury column reaches

In the case of building a barometer with a liquid that has a density greater than that of mercury

            ρ_liquid > ρ_Hg

             

the pressure

              P =ρ_lquid g h_liquid

if we have the same pressure

            ρ_{Hg} g h_{Hg} = ρ_{liquid}  g h_{liquid}

            h_{ liquid} = [tex]\frac{\rho_{Hg} }{\rho_{liqid}} \ h_{Hg}[/tex]

therefore the liquid has less height than the mercury
