Determining number of moles of Hexanal, C6H12O
given: Mass = 523.46g
Molecular Mass(C6H12O) =(C*6 +H*12 + O)
=(12.0107*6 +1.00794*12 +15.999)
=100.16g/mol
Using the formula: number of moles,n = Mass/Molecular Mass
n= 523.46g/100.16g/mol
=5.23moles
This means that number of moles for C6H12O is 5.23moles
