Question

From the following observations, calculate the density and relative density of a brine solution. Mass of empty density

bottle = 22 g

Mass of bottle + water = 50 g

Mass of bottle + brine solution = 54 g

Answer 1

Mass of empty bottle, M₁ = 22 g

Mass of bottle + water, M₂ =50 g

Mass of bottle + brine solution, M₃ = 54 g

Mass of water = M₂ — M₁ = 50—22 = 28 g

Mass of brine solution = M₃ — M₁= 54—22 = 32 g

Density of brine solution = Mass of brine solution / Mass of water

= 32/28 = 1.14 g/cm³
