Percent yield represents to what extent the reaction runs to completion. In this, the theoretical yield is 50 grams (100% completion).
To calculate percent yield, divide the actual by the theoretical. In doing so, the percent yield is 88% (44/50).
Answer:
<h2>A. Mercury's orbit is shorter than Earth</h2>
Answer: A volume of 455 mL from 0.550 M KBr solution can be made from 100.0 mL of 2.50 M KBr.
Explanation:
Given:
= ?,
= 0.55 M
= 100.0 mL,
= 2.50 M
Formula used to calculate the volume of KBr is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that a volume of 455 mL from 0.550 M KBr solution can be made from 100.0 mL of 2.50 M KBr.
