Question

Martina has a sample of an unknown substance. She measures the substance. Its mass is 13.5 grams, and its volume is 5 cm3. Which metal might her sample be made of?

Answer 1

the answer is aluminum.

Answer 2

Answer : Aluminium.

Explanation : To find the correct answer we can find out the density of the sample,

Using the density formula which is,

Density ρ =
`(mass (m))/(volume (v))`

Here, Mass = 13.5 g; Volume = 5
`cm^(3)`

on calculating we get,

Density =
`(13.5)/(5) = 2.7 g/cm^(3)`

Which shows that, aluminum has this density. Aluminum has density as
`2.7 g/cm^(3)`

So, the correct answer will be aluminum.
