To convert 3.01 x 10^23 molecules of C2H6 to moles, we need to use Avogadro's number, which is 6.022 x 10^23 molecules/mol.
First, determine the number of moles in 3.01 x 10^23 molecules of C2H6 by dividing the given number of molecules by Avogadro's number:
3.01 x 10^23 molecules / 6.022 x 10^23 molecules/mol = 0.5 moles
Therefore, 3.01 x 10^23 molecules of C2H6 is equivalent to 0.5 moles.
This conversion is essential in chemistry to relate the microscopic scale of individual molecules to the macroscopic scale of moles, making it easier to quantify and compare substances by their amount. Understanding and applying Avogadro's number is crucial in various chemical calculations, enabling chemists to work with consistent and standardized units for accurate analysis and prediction.
