Question

from the following observations, calculate the density and relative density of brine solution.
a) mass of empty density bottle= 22g
b) mass of bottle+water= 50g
c) mass of bottle +brine solution = 54g

Answer 1

Answer:

Density = 8/7 g/cm³

Relative Denisty = 8/7

Step-by-step explanation:

calculate the density and relative density of a brine solution

1.Mass of empty density bottle=22g

2. Mass of bottle +water=50g 3.

Mass of bottle + brine solution=54g

Mass of bottle +water=50g

=> Mass Of Water = 50 g - Mass of Bottle

=> Mass Of Water = 50 - 22  = 28 g

Mass of bottle + brine solution=54g

=> Mass Of brine solution = 54 g - Mass of Bottle

=> Mass Of  brine solution = 54 - 22  = 32 g

Let say Volume of Bottle = V

Density of Water = 28/V  =  1 g/cm³

=> V = 28 cm³ = 28 ml

Density of Brine Solution =  32/28  = 8/7 g/cm³

Relative density of Brine Solution = (8/7)/1  = 8/7
