Answer:
d) The dilution equation works because the number of moles remains the same.
Explanation:
Let’s say that you have 1 mol of a solute in I L of solution. The concentration is 1 mol·L⁻¹. and <em>M</em>₁<em>V</em>₁ = 1 mol.
Now, you dilute the solution to a volume of 2 L. You still have 1 mol of solute, but in 2 L of solution. The new concentration is 0.5 mol·L⁻¹.
The volume has doubled, but the volume has halved, and <em>M</em>₂<em>V</em>₂ = 1 mol.
b) <em>Wrong</em>. The molar concentration changes on dilution.
c) <em>Wrong</em>. The volume changes on dilution.
a) <em>Wrong</em>, although technically correct, because if the moles don’t change, the mass doesn’t change either. However, the formula <em>M</em>₁<em>V</em>₁ has units mol·L⁻¹ × L = mol. Thus, in the formula, it is moles that are constant.
The answer for the equation given is 1.743488.

10,000/ 5,735.63 = 1.743488.
<h3>How are units labeled?</h3>
Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.
<h3>What is label in math means?</h3>
A graph labelling is the process of assigning labels, which are typically represented by integers, to the edges and/or vertices of a graph in the field of mathematics known as graph theory.

Convert metres to feet:
343m*3.28f = 1,125.04ft/s
There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.
1,125.04ft*3600s = 4,050,144 ft/h
Now, since you asked for miles, convert to miles (5280 ft in a mile):
4,050,144ft/5,280m = 767.072mph
That is your answer! Hope I helped. :)
