Sulphur trioxide is prepared by the following two reactions: S_(8(s))+8O_(2(g))to8SO_(2(g)),2SO_(2(g))+O_(2(g))to2So_(3(g)) How many grams of SO_(3) are produced from 1.6 g S_(8) ?

Sulphur trioxide is prepared by the following two reactions: S_(8(s))

1.	Sulphur trioxide is prepared by the following two reactions: S_(8(s))+8O_(2(g))to8SO_(2(g)),2SO_(2(g))+O_(2(g))to2So_(3(g)) How many grams of SO_(3) are produced from 1.6 g S_(8) ?
Answer» SOLUTION :`S_(8(g))+8O_(2(g))rarr8SO_(2(g))` `256g_______8xx64=512g` `1.6g_______3.2g` `2SO_(2(g))+O_((2)g)rarr2SO_(3(g))` `2xx64` `=128g______2xx80=160g` `3.2g______(3.2xx160)/(128)=4G`
