You're starting with
(12.0 mL) (0.550 M) = (0.0120 L) (0.550 M) = 0.00660 mol
of FeCl₃.
For every mole of FeCl₃ in the balanced reaction, you need 3 moles of NH₄OH, so you need a minimum 0.0198 mol NH₄OH per mole FeCl₃.
Then the requisite volume of NH₄OH solution needed is <em>V</em> such that
(0.0198 mol) / <em>V</em> = 0.200 M
Solve for <em>V</em> to get
<em>V</em> = (0.0198 mol) / (0.200 M) = 0.0990 L = 99 mL
Answer:
A lot
Explanation:
Plenty means like to much or a lot
Ex: My mom gave me plenty of chips.
I believe that A would be your answer because 3.25 + 2.25 + 1.50 = 7 and four percent of seven would be $1.05 and tip is $.28 cents
The second one is C
Hope this helped :)
yes it would by the heat
