Answer:8.12 x 10^23 molecules of CO2 gas contain 1.35 moles
Explanation:To calculate the number of moles in a given number of molecules, you can divide the number of molecules by Avogadro's number:
1.35 mol = 8.12 x 10^23 molecules / 6.022 x 10^23 molecules/mol
Avogadro's number is 6.02 x 10^23, which indicates the number of atoms, molecules, and other things in one mole of a given material.
To calculate the mass of 1.35 moles of CO2, you can multiply the number of moles by the molecular weight:
1.35 mol x 44.01 g/mol
The molar mass of carbon dioxide is 44.009 g/mol. This is the mass in one mole of the compound.
