Formula:

Given:
Density=3.4
Volume=500.0
Plug them into the formula:
Final answer: 1700g
<span>0.38
You first calculate the total moles by dividing the grams by molecular weight:
45 g N2 / 28.02 g/mol = 1.6 mol N2
40 g Ar / 39.95 g/mol = 1.0 mol
Then you divide the moles of Ar by the total number of moles:
1.0 / (1.6 + 1.0) = 0.38 mol fraction</span>
Answer:
I believe it is kinetic energy
Hope this is right .-.
