Question

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

were recorded.
-mass of an empty beaker = 65gm.
- mass of the beaker and water = 165gm.
the volume of water = 100Cm.
(Calculate the density of water)​

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 =
`(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 =
`(100g)/(100cm^(3) )`

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