<u>We can use the </u><u>formula.</u><u> </u>
c1v1 =c2v2
<u>Where c1 is the concentration and v1 is volume of the concentrated </u><u>solution.</u><u> </u>
c2 is the concentration
and v2 is the volume of the diluted solution to be prepared
9.00 M x V1 = 2.75 M x 350 mL
V1 = 106.9 mL
<u>Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 </u><u>mL</u><u>.</u>
19 in = 1.6 ft
You know that
12 in = 1 ft
If you divide both sides by 12 in, you get the <em>conversion factor</em>: 1 = 1 ft/12 in.
If you divide both sides by 1 ft, you get the <em>conversion factor</em>: 12 in/1 ft = 1.
Both are conversion factors because they <em>both equal one</em> and <em>multiplying a measurement by one does not change its value</em>.
You choose the conversion that gives you the correct dimensions for your answer. It must have the correct dimensions <em>on top</em> (in the numerator),
Thus, to convert 19 in to ft, you use the conversion factor with “ft” on the top.
∴ Length = 19 in × (1 ft/12 in) = 1.6 ft
