Given parameters:
mass of an empty beaker = 65gm
mass of the beaker and water = 165gm
volume of water = 100cm³
Unknown:
Density of water = ?
Solution:
Density is the mass per unit volume of a substance;
Density =
To find the mass of the water ;
Mass of water = Mass of beaker and water - mass of an empty beaker
= 165g - 65g
= 100g
So input parameters and solve;
Density =
Density of the water in the beaker = 1g/cm³
