1 mole => 6.023 x 10^23 molecules

x => 8.5 x 10^25 molecules

x = 8.5x10^25/ 6.023 x 10^23 = 141.1

Step-by-step explanation:

According to the mole concept, there are
6.022 * 10^(23) atoms present in 1 mole of a substance.

Mathematically, 1 mole =
6.022 * 10^(23) atoms or molecules

Therefore, calculate the number of moles of
CO_(2) present in
8.5 * 10^(25) molecules as follows.


(8.5 * 10^(25))/(6.022 * 10^(23))

=
1.411 * 10^(2) mol

or, = 141.1 mol

Thus, we can conclude that there are 141.1 moles present in
8.5 * 10^(25) molecules of
CO_(2).
