The correct answer is 1. compound. There are three elements and not just one so it's not element. Mixtures wouldn't have the same properties that you described but these do so it's a compounds. Solution is not a solid thing but rather a liquid one. The two samples are therefore compounds.

Find the density of a substance that has a mass of 75 g and a volume of 35 mL. Don't forget your units!

Andrew [12]

Answer:

The density of a substance that has a mass of 75 g and a volume of 35 mL is 2.14 $\frac{g}{mL}$

Explanation:

Density is a characteristic property of a substance that relates to the amount of mass it has per unit volume. In other words, density is the property that matter, whether solid, liquid or gas, has to compress into a given space (it measures the amount of mass in a given volume of a substance). It is calculated as the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$
