Answer:

C) 5 moles of Argon (Ar)

Explanation:

5mol Na x 22.990g Na/ 1 mol Na = 114.95g Na

5mol P x 30.974g P/ 1 mol P = 154.87g P

5mol Ar x 39.948g Ar/ 1 mol Ar = 199.74g Ar

Therefore Ar has the greatesr mass.

snow_lady [41]
Thank you for posting your question here at brainly. Below is the solution:

 <span>moles HClO4 = 0.100 L x 0.18 M = 0.018 
moles LiOH = 0.030 L x 0.27 = 0.0081 
moles H+ in excess = 0.018 - 0.0081 = 0.0099 
total volume = 0.130 L 
[H+] = 0.0099/ 0.130= 0.0762 M 
pH = 1.12</span>

F.
it's the greatest electron "hogger"
as you get closet to it, the stronger the electro negitivity.
He is halogen : they don't like to gain electrons. they are already stable.
