2.71 x 10²² molecules of CO2 is equivalent to 2.71 x 10²² atoms.
<h3>What is number of molecules?</h3>
The number of molecules in an element is the combination of atoms in that element.
The number of molecules of an element can be calculated by multiplying the number of moles of that element by Avogadro's number, which is 6.02 × 10²³.
However, the number of molecules in a substance is equivalent to the number of atoms in that substance.
Therefore, 2.71 x 10²² molecules of CO2 is equivalent to 2.71 x 10²² atoms.
