Answer:
A compound
Explanation:
Chemical compound can be regarded as any substance made up of identical molecules which consists atoms of two or more than two chemical elements. For example four hydrogen atoms bonds with a carbon atom to give methane molecule which is a compound. It should be noted that A compound is a new substance with unique chemical and physical properties formed when two or more elements are chemically bonded during a physical reaction.
Boiling-point<span> elevation describes the phenomenon that the </span>boiling point<span> of a liquid (a </span>solvent<span>) will be higher when another compound is added, meaning that a </span>solution has<span> a higher </span>boiling point<span> than </span>a pure solvent<span>. This happens whenever a non-volatile solute, such as a salt, is added to </span>a pure solvent<span>, such as water.
So the correct answer is C.</span>
To determine this all you would need to do is rearrange the equation for density and solve for the value of volume. Then plug in the numerical values into the equation and solve for v.
D = m/v
Dv = m
V = m/D
V = 15.7 g/2.50 g/cm^3.
V = 6.28 ml.
Answer:
