Question

A sample of gold has a mass of 38.6 grams and a volume of 2cm. What is the density of gold?

Answer 1

given:

mass of the sample gold= 38.6g

volume =

`2 {cm}^(3)`

to find:

the density of the gold.

solution:

D = m/V

`m = 38.6g`

`= 0.0386kg`

`v = 2 {cm}^(3)`

`= 0.000002 {m}^(3)`

then substitute the values.

`d = (0.0386)/(0.000002)`

`d = 19300kg | {m}^(3)`

therefore, the density of the sample gold is 19300kg/m3
