Answer 2

Given: $12.044×10^{23}$ molecules of carbon dioxide.

To find: We have to find the number of moles.

Solution:

The chemical formula of carbon dioxide is $CO_2$.

The atomic mass of C is 12 and the atomic mass of O is 16 amu.

Thus, the molecular mass of methane is 12+16×2=44 amu.

Thus $6.022×10^{23}$ number of molecules of carbon dioxide occupy one mole.

Thus $12.044×10^{23}$ number of molecules of carbon dioxide occupy $12.044×10^{23}/6.022×10^{23}×16=2$ moles.

Thus the moles of $12.044×10^{23}$ molecules of carbon dioxide is 2.
