The density of liquid gallium at 30^(@)C...

The density of liquid gallium at `30^(@)C` is 6.095 g/mL. Because of its wide liquid range (30 to `2400^(@)C`), gallium is used as a barometer fluid at high temperature. What height (in cm) of gallium will be observed on a day when the mercury barometer reads 740 torr? `
` (The density of mercury is 13.6 g/mL.)

A

322

B

285

C

165

D

210

Text Solution

Verified by Experts

The correct Answer is:
c
(c) `h_("Galium")=(74xx13.6)/(6.095)=165.1`
