Помогите посчитать AI2O3; SO2; H2SO4 по формуле( на фото) Срочно!!!!

W(Al) = 53% W(O) = 47% W(S) = 50% W(O) = 50% W(H) = 2%  W(S) = 32% W(O) = 65%

M(Al2O3)=27*2+16*3=102 g/mol W(AL)=27*2/102*100%=53% W(O)=16*3/102*100% = 47%   M(SO2)=32+16*2 = 64 g/mol W(S) = 32/64*100% = 50% W(O2)=16*2/64*100% = 50% M(H2SO4)=1*2+32+16*4=98 g/mol W(H)=1*2/98*100%=2.04% W(S)=32/98*100%=32.65% W(O)=16*4/98*100%=65.31%
