Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock 
solution = 10.0 M
= volume of stock solution = ?
= molarity of dilute solution = 0.50 M
= volume of dilute solution = 4.0 L
Therefore, the volume of 10.0 M solution needed to prepare 4.0 L of 0.50 M is 0.20 L
The density of a plasma can be described as : ( A ) Low density
<h3><u>Density </u></h3>
Density is the mass per unit volume of a substance, it is used for comparison between substances because the mass and volume which are scalar quantities of substances are applied.
The density of plasmas are low when compared to solids because the volume occupied by a plasma of the same mass as a solid, is greater when compared to the volume occupied by a solid.
Hence we can conclude that The density of a plasma can be described as Low density.
