In 1958, the carbon dioxide level measured in Earth's atmosphere was about 315 parts per million (ppm). In 2000, the carbon dioxide level in the atmosphere had increased to about 368 ppm. What was the average annual increase in carbon dioxide in the atmosphere between 1958 and 2000 measured in ppm? What possible explanation is there for the increase in atmospheric carbon dioxide?

more info ? ? i don't understand what the question is

explanation:

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

there is none because earth is stationary and flat.
