Asample has a mass of 7.412 grams and a volume of 0.217 liters. what is the density of this sample?

Answer : The density of a sample is, 34.2 g/L

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used for density :

Given :

Mass of a sample = 7.412 grams

Volume =0.217 L

Now put all the given values in the above formula, we get the density of a sample.

Therefore, the density of a sample is, 34.2 g/L

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
