Answer: 9.93 x 10^23 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of carbon dioxide = 6.02 x 10^23 atoms
1.65 moles = Z atoms
To get the value of Z, cross multiply:
Z atoms x 1mole = (6.02 x 10^23 x 1.65)
Z = 9.93 x 10^23 atoms
Thus, there are 9.93 x 10^23 atoms of carbon dioxide.
