Question

(1) In an experiment for determining the density of water, the following results

Answer 1

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  = $\frac{mass}{volume}$

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  =  $\frac{100g}{100cm^{3} }$  

         Density of the water in the beaker  = 1g/cm³
