Anonrenewable resource is a natural resource that cannot be replaced once it is used. which is a nonrenewable resource?

The most common examples of non-renewable resources are fossil fuels, such as coal, oil and natural gas. Although these resources form naturally within the earth, they take billions of years to do so. Other non-renewable resources include metals, minerals and stone.

Although fossil fuels are continually being formed via natural processes, they are generally considered to be non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made.

b.

the accuracy of the data.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
