N = ?
T = 449 K
V = 58.35 L
P =2.97
R = 0.082
Use the clapeyron equation:
P x V = n x R x T
2.97 x 58.35 = n x 0.082 x 449
173.2995 = n x 36.818
n = 173.2995 / 36.818
n = 4.70 moles

Answer:
B: Adding water, then adding solute
Explanation:
This is because, say you have a solution with a certain concentration.
If you add more water, it will become more diluted (less concentrated)
If you add more solute, it will become more concentrated.
Therefore if you add water and solute, it could cancel out, and the concentration would remain the same.
Hope this helps! Let me know if you have any questions/ would like anything further explained :)
Answer: Gravity.
Explanation:
Earth and other objects would have fly off into space in a straight line if there would have been no gravity in between objects.
The gravity can be defined as the force between two objects in space which keeps two objects together in the space.
It is also responsible for holding the objects in space, making them move on their orbits, not allowing the heavenly bodies to crash.
So, there would be no gravity the objects will fall off in a straight line and none of the objects would be at its specified position.
Electrons have a mass of 1/1836
Hope that helps you!
