How many moles are there in 8.5x 1025 molecules of co2

Explanation:

According to the mole concept, there are present in 1 mole of a substance.

Mathematically,    1 mole = atoms or molecules

Therefore, calculate the number of moles of present in molecules as follows.

                 = mol

or,              = 141.1 mol

Thus, we can conclude that there are 141.1 moles present in molecules of .

c) should be the answer.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
