When calculating the number of moles of CO₂ and Hg, we have:
a) There are 4.02 moles of CO₂ in 2.42x10²⁴ molecules.
b) There are 0.010 moles of Hg in 6.23x10²¹ atoms.
a) The number of moles of CO₂ that are in 2.42x10²⁴ molecules can be calculated with Avogadro's number (N = 6.022x10²³)
[tex] n = \frac{1 mol}{6.022 \cdot 10^{23} \:molecules}*2.42 \cdot 10^{24} \:molecules = 4.02 moles [/tex]
Hence, the number of moles of CO₂ is 4.02.
b) To find the number of moles of Hg equivalent to 6.23x10²¹ atoms, we need to use Avogadro's number:
[tex] n = \frac{1 mol}{6.022 \cdot 10^{23} \: atoms}*6.23 \cdot 10^{21} \: atoms = 0.010 moles [/tex]
Therefore, the number of moles of Hg is 0.010.
