Answer:
Explanation:
Given:
- volume of liquid content in the can,
- mass of filled can,
- weight of empty can,
<u>So, mass of the empty can:</u>
<u>Hence the mass of liquid(soda):</u>
<u>Therefore the density of liquid soda:</u>
(as density is given as mass per unit volume of the substance)
<u>Specific weight of the liquid soda:</u>
Specific gravity is the density of the substance to the density of water:
where:
density of water
