Explanation:
Hope this helped! :)
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:
So therefore, we now know that the density of carbon dioxide gas is 0.00196g/mL.
First put the choices,and the answer is <span>(10^-3L/1mL)^3 is the correct answer.</span>
The answer should be "by convection" not by radiation.
