Question

the mass of a density bottle is 25 gram 150 gram when will completely fill water in 365 gram and feel completely with Mercury find the density of Mercury

Answer 1

Explanation:

density is given by mass/volume ..

mass of mercury is 365g-25g=340g.

then volume to be used will be:

150g -25gto get 125g as the mass of water....mdensity of water is usually 1g/cm cubic hence volume will be 125/1 =125cm cubic....the volume of water is the volume of the density bottle....volume of density bottle is volume of mercury too...it is 125 cm cubic hence 340g/125cm cubic =2.72g/cm cubic

Answer 2

Step by step explanation

Mass of empty bottle = 25g
Mass of empty bottle + water = 150g
Mass of empty bottle + Mercury = 365g

Mass of only water = Mass of bottle with water - Mass of empty bottle
= 150g - 25g
= 125g
Mass of only mercury = Mass of bottle with mercury - Mass of empty bottle
= 365g - 25g
= 340g

Now 1g of water = 1 cubic cm of water

Volume of water = 125 cubic cm
Volume of mercury = volume of water = 125 cubic cm

Density of mercury = Mass of mercury / Volume of mercury
= 340g/125cubic cm
= 2.72 g/cm^3


Answer is 2.72g/cm^3.
