Best ResponseYou've already chosen the best response.1\[\Delta S _{products} = ( 2 * 28Jmol ^{1}K ^{1}) + (3 * 189Jmol ^{1}K ^{1})\]

Best ResponseYou've already chosen the best response.1The entropy given for each is for 1 mole right? Since Al has 2 moles u multiply it by 2 Since H2O has 3 u multiply it by 3 Up to now do u get it ?
