Question

Liquid isopropyl iodide has a density of 1.70 g/mL. A barometer is constructed using isopropyl iodide instead of mercury. If the atmospheric pressure is 0.951 atm, what is the height of the isopropyl iodide column in the barometer in cm? The density of liquid mercury is 13.6 g/mL.

Answer 1

the height of the isopropyl iodide column in the barometer in cm =578.208 cm

Step-by-step explanation:

Pressure of the liquid column=ρgh

ρ= density of the liquid

h= height of the column

g= acc. due to gravity

height of the mercury column corresponding to 0.951 atm

= 0.951×76/1atm = 72.276 cm

since, pressure to be measured is same

1= mercury

2=isopropyl iodide

`\rho_1h_1g=\rho_2h_2g`

`\rho_1h_1=\rho_2h_2`

`13.6(72.276)=1.70*h_2`

h2= 578.208 cm

the height of the isopropyl iodide column in the barometer in cm =578.208 cm
