The mass of a density bottle is 25 g when empty, 50 g when filled completely with water and 365 g when filled completely with mercury. Find the density of mercury.

Text Solution

Verified by Experts

mass of water`=50g-25g=25g`
mass of an equal volume of mercury`=365g-25g=340g`
Relative density of mercury`=(340g)/(24g)=13.6`
density of mercury`=13.6xx`density of water (at`4^@`C)
`13.6xx1000(kg)/(m^3)=13600(kg)/(m^3)`
