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.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
