Explanation:
According to the mole concept, there are \(6.022 \times 10^{23} atoms\) present in 1 mole of a substance.
Mathematically, 1 mole = \(6.022 \times 10^{23}\) atoms or molecules
Therefore, calculate the number of moles of \(CO_{2}\) present in \(8.5 \times 10^{25}\) molecules as follows.
\(\frac{8.5 \times 10^{25}}{6.022 \times 10^{23}}\)
= \(1.411 \times 10^{2}\) mol
or, = 141.1 mol
Thus, we can conclude that there are 141.1 moles present in \(8.5 \times 10^{25}\) molecules of \(CO_{2}\).
