Answer:
Nitrogen and Oxygen make up 99% of the Earths atmosphere. Then Argon makes up the rest of the atmosphere.
The arctic climate most likely
Answer:
these elements do not have the same masses.
We know that the equation for density is:

where D is the density, m is the mass in grams, and V is the volume.
Given two of the variables, we can then solve for density:

Therefore, we now know that the density of the gasoline is 0.833g/mL.
