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.

Answer 1

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
