Question

Сульфат алюминия w(al) ? w(s)? w(o)?

Answer 1

Mr(Al2(SO4)3)=27*2+32*3+16*12=342
W(Al)=Ar(Al)*n/Mr(Al2(SO4)3. *100%=27*2/342 *100%=16%
W(S)=Ar(S)*n/Mr(Al2(SO4)3) *100%=32*3/342 *100%=28%
W(O)=Ar(O)*n/Mr(Al2(SO4)3 *100% =16*12/342 *100%=56%

Answer 2

The chemical formula for aluminum sulfate is Al2(SO4)3. In the context of the subscripts (w(al), w(s), w(o)), it seems like you might be referring to the physical states of the substance in different forms.

• w(al): This likely represents aluminum in its solid state (Al(s)), where "s" stands for solid.

• w(s): This could represent sulfate in its solid state (SO4(s)), where "s" stands for solid.

• w(o): This could represent aluminum sulfate in its solid state (Al2(SO4)3(s)), where "s" stands for solid.

Please note that without additional context or explanation, it's not entirely clear what these symbols are meant to represent. If you have a specific question or require further clarification, feel free to provide more information.
