The density of mercury is 13.5 g/mL and the density of water is 1.00 g/mL. If a mercury barometer reads 805 mmHg, what is the ba

Marina86 [1]

Answer:

Barometric pressure will be $1086.75 cm H_{2}O$

Explanation:

We know, $P=h\rho g$

where P is barometric pressure, h is height of liquid inside barometer, $\rho$ is density of liquid and g is gravitational constant

If barometric pressure is x cm $H_{2}O$ for 805 mm Hg then-

$x\times (1.00g/mL)\times g=(805\times 10^{-1}cm Hg)\times (13.5g/mL)\times g$

So, $x=1086.75 cm H_{2}O$

Hence barometric pressure will be $1086.75 cm H_{2}O$
