The autonomic nervous system has a direct role in physical response to stress and is divided into the sympathetic nervous system (SNS), and the parasympathetic nervous system (PNS). When the body is stressed, the SNS contributes to what is known as the “fight or flight” response.

Explanation:
First, we need to convert 50.0 mL to L.
1 mL = 0.001 L
50.0 mL = 0.05 L
Now, we need to find the number of moles of CuSO4 when given 10.0 grams of the compound.
159.609 grams CuSO4 = 1 mol CuSO4
10.0 grams CuSO4 = 0.0627 mol CuSO4
Now, we can plug in this information into the formula.
So, the molarity of copper (II) sulfate is 1.254 when given a 50.0 mL aqueous solution.
