Question

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

• A. 7.3 g/cc
  
• B. 113.6 g/cc
  
• C. 13.6 g/cc
  
• D. 14.6 g/cc
  

Answer 1

The correct option is C 13.6 g/cc

density = mass/ volume

mass of empty bottle$=25g$

mass of bottle filled with water$=50g$

mass of liquid $=25g$

volume of liquid$=25ml$

volume of mercury$=25ml$

mass of mercury$=365-25=340g$

density of mercury$=340/25=13.6$ g/${cm}^3$
