Answer:
Ok to solve this you will need to use the Ideal Gas Law Formula which is as follows:
PV = nRT
P= pressure
V= volume
n= # of moles
R= Universal Gas Constant (0.0821 L x atm/mol x K)
T= Kelvin temperature
1.Simplify the Ideal Gas Law formula to what you need to solve for:
P = (nRT)/ V
2. List all you components as follows (this makes the process easier):
P = ?
V = 45.4 L
n = 0.625 mol
R = 0.0821 L x atm/ mol x K
T = 249 K
To find the Kelvin temperature K = C + 273
3. Plug in all your components in your set up formula:
P = [(0.625 mol)(0.0821 L x atm/ mol x K)(249 K)] / (45.4 L)
4. Cross out all similar units so the only thing left is atm because you are trying to find pressure.
P = [(0.625)(0.0821atm)(249)] / (45.4)
5. Multiply through and simplify
P = 0.28 atm
B. is the correct answer.

Explanation:
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.
