Sum

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

#### Solution

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/cm^3
