Answer:
its average per average is 0.5
Explanation:
when 2 average is 1 and 1 average is0.5
The molar concentration of the solution.
Answer:
c. temperature and water vapor content.
Explanation:
The density of any substance is dependent of temperature, and in gases, the variations is greater than in any other substance, therefore, temperature is very important to calculate air density. Also, the concentration of water vapor in the air can vary depending where is located, and that concentration will affect the density because it affects the average mass of air.
