What is the mass of 0.5 moles of carbon tetrafluoride, CF4?

44.0015

Explanation:

we go and look at the mass for carbon which is 12.011 then at the mass of fluorine which is 18.998. Since there are 4 Fluorines the we multiply 4 by 18.998 which we get 75.992. Then we add 75.992 + 12.011 which will give us 88.003 then multiply 88.003 by 0.5 which gives us 44.0015

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
