Answer:
B
Explanation:
Molarity measures the strength of a solution. Remember, a solution is made up of two parts: the solvent (which does the dissolving) and the solute (the substance that is dissolved). The more solute there is, the higher the concentrate and therefore the higher the molarity of the solution. Thus B is the answer
<span>Density is a physical
property of a substance that represents the mass of that substance per unit
volume. It is a property that can be used to describe a substance. We calculate the volume as follows:
21 grams Ag ( 1 L / 10.5 grams ) = 2 L of container is needed for the given mass of silver
Hope this answers the question. Have a nice day. </span>
