Answer:
A
Explanation:
Got a calculation of 8.05297
Volume = 250 mL in liters : 250 / 1000 => 0.25 L
Molarity = 0.85 M
Number of moles:
n = M x V
n = 0.85 x 0.25
n = 0.21 moles
Choice B
"People should remove native plants around watersheds" option should a person avoid doing in order to better protect the quality of watersheds.
<u>Option: A</u>
