  • First, 
    we calculate the mass of the compound 
    2 Al atoms x 26.98 g = 53.96 g 
    3 S atoms x 32.07 g = 96.21 g 
    12 O atoms x 16.0 g = 192 g 
    Total = 342.17 g 

    For % O, divide the mass of O in compound by the total and multiply by 100 % 
    (192g / 342.17g) (100%) = 56.11% O
  • similarly  
  • for % Al = 15.745
  • for % s = 28.118
