When a solution is diluted, what is the relationship of the number of moles of solute in the more concentrated initial volume of
solution to the number of moles of solute in the less concentrated final volume of solution? A. The ratio of the numbers is directly proportional to the two volumes. B. The ratio of the numbers is inversely proportional to the two volumes. C. The number of moles of solute in the more concentrated initial volume is always greater. D. The number of moles of solute in the less concentrated final volume is always greater. E. The number of moles of solute in both solutions is the same.
E. The number of moles of solute in both solutions is the same.
Explanation:
The dilution of a solution consist in increase the volume of solution decreasing, thus, the concentration of the solution. The moles of solute doesn't change in a dilution process.
Thus, when a solution is diluted, the relationship of the number of moles of solute in the more concentrated initial volume of solution to the number of moles of solute in the less concentrated final volume of solution is that:
E. The number of moles of solute in both solutions is the same. TRUE.
There might not be ample enough wind to power all the electricity in the United States and in some places there might not be wind at all so people wouldn't be able to have electricity.
