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 : Aluminium.

Explanation : 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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
