Question
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 volume of density bottle.
Solution
Mass of empty density bottle (M1) = 30 g
Mass of bottle + Water (M2) = 75 g
Mass of liquid + Liquid (M3) = 65 g
Mass of water = M2 - M1
= 75 - 30
= 45 g
Volume of density bottle = Mass of water = 45 g
∴ 1 g = 1 mL
Volume of density bottle = 45 g = 45 mL
∴ Volume of density bottle = 45 mL
