Question

10. 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

Answer:

Mass of empty bottle , M

1

= 22 g

Mass of bottle + water , M

2

= 50 g

Mass of bottle + brine solution , M

3

= 54 g

Mass of water = M

2

−M

1

=50−22=28g

Mass of brine solution = M

3

−M

1

=54−22=32g

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

=

28

32

=1.14g/Cm
