Question

The number of cubic centimeters of gold in 4.18x10^3 of gold is:(density of gold 19.3g/cm^3)?
a) 514cm^3
b) 217 cm^3
c) 417 cm^3
d)110 cm^3
if you know the answer please explain how you got it
thank u

Answer 1

its 216.58cm^3

Its simple :
In simple terms density 19.3 g/ cm^3 means u have 19.3 gram of gold in 1 cm^3

So now u have 4.18x10^3g of gold.
So by unitary method [4.18x10^3g]/19.3 g/ cm^3 which gives to 217cm^3.

Hope u got it .....
