A metal cup full of water has a mass of 1,000 g. The cup itself has a mass of 214.6 g. If the cup has both a diameter and a height of 10 cm, what is the approximate density of water?

Answer: Approximate density of water is 1 g/cm³.

Explanation:

Since we have given that

Mass of metal cup full of water = 1000 g

Mass of cup = 214.6 g

So, Mass of water = Mass of filled cup - Mass of empty cup

Mass of water = 1000 g - 214.6 g

Mass of water = 785.4 g

Diameter of cup = 10 cm

Radius of cup = 5 cm

Height of cup = 10 cm

So, volume of cup is given by


\pi r^2h\\\\=(22)/(7)* 5^2* 10\\\\=(22)/(7)* 250\\\\=785.71\ cm^3

so, Density of water would be


(Mass)/(Volume)\\\\=(785.71)/(785.4)\\\\\approx 1\ g/cm^3

Hence, approximate density of water is 1 g/cm³.
