The molar mass of aluminum (Al) is 26.98 grams per mole (g/mol). To convert 62.13 kg of Al to moles, we need to divide the mass in kilograms by the molar mass in grams per mole and then convert the result to moles.

$$ Moles \ of \ Al = \frac{Mass \ of \ Al \ (kg)}{Molar \ Mass \ of \ Al \ (g/mol)} \times \frac{1000 \ g}{1 \ kg} $$

$$ Moles \ of \ Al = \frac{62.13 \ kg}{26.98 \ g/mol} \times \frac{1000 \ g}{1 \ kg} $$

$$ Moles \ of \ Al = 2306.14 \ moles $$

Therefore, 62.13 kg of Al is equal to 2306.14 moles of Al.
