प्रश्न
The mass of an empty density bottle is 30 g, it is 75 g when filled completely with water and 65 g when filled completely with a liquid. Find density of liquid.
उत्तर
Mass of empty density bottle (M1) =30 g
Mass of bottle + Water (M2) 75 g
Mass of liquid x + density bottle (M3)= 65 g
mass of density bottle - liquid x = 30g - 65g =35g
Mass of water=M2—M1=75—30=45 g
Density of Iiquid x = ?
D= `("Mass of Liquid") /("Mass of water")`=`35/45`
Mass of liquid =`M_3`-`M_1`=65-30=35 g
D=` ("Mass of liquid")/("Mass of water")`=`35/45`=0.77 g/`cm^3`
