answer : E) .54.0 grams

the balanced reaction is :

mass of HCl = 8.88 x 10^4 mg

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 88.8 g

2KMnO4 (aq) + 16HCl (aq) -------------> 2KCl (s) + 2MnCl2 (aq) + 8H2O (l) + 5Cl2 (g)

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 584 gÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 355 g

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 88.8 gÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ??

according to balanced equation :

584 g HClÂ Â ---------------> 355 g Cl2

88.8 g HCl -------------->Â Â ?? g Cl2

mass of Cl2 gas = 88.8 x 355 / 584

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 54.0 grams

mass of chlorine gas = 54.0 grams
