Answer:
0.508 L of solution.
Explanation:
Always a safe bet to convert to moles:

Where n is moles, m is mass, and MM is molar mass.
Now remember the equation for concentration (molarity):

Where C is the concentration, n is moles, and V is volume.
To make this easy, combine the two equations (note n appears in both, so you can do a substitution) and solve for V as the question asks:

Therefore we can make 0.508 L of solution.
Explanation:
Once the earth's atmosphere was formed it really hasn't changed since, this is due to many reasons. Whatever created the earth's atmosphere (we don't know) has long disappeared, because of this the atmosphere cannot change, as there is nothing on earth that can change it (that we know of at least). Hopefully this helps.
