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

Aluminium, To find the correct answer we can find out the density of the sample,
Using the density formula which is,
Density ρ =
Here, Mass = 13.5 g; Volume = 5
on calculating we get,
Density =
Which shows that, aluminum has this density. Aluminum has density as
So, the correct answer will be aluminum.
