Question

Conver 100 g Al to mol

Answer 1

To go from moles to grams, we must divide the given grams by the molar mass of the element. The molar mass of aluminum Al is 26.98g/mol. So the moles of Al will be:

`molAl=givengAl*(1molAl)/(MolarMass,gAl)`
`molAl=100gAl*(1molAl)/(26.98gAl)=3.71molAl`

Answer: 100 grams Al are equal to 3.71 moles of Al
