How many moles are in 4177g of aluminum chloride

The mole is the unit of measurement in the International System of Units (SI) for amount of substance. It is defined as the amount of a chemical substance that contains as many representative particles, e.g., atoms, molecules, ions, electrons, or photons, as there are atoms in 12 grams of carbon-12 (12C), the isotope of carbon with relative atomic mass 12 by definition. 
so to solve the moles, divide the mass with molar mass

moles = 4177 g / 133.34 g/mol
moles = 31.33 moles

100%sorry if i’m wronghope this good luck: )
