Answer 1

Nags 189 & Cusou 159.69 Nag sou tous 142g 95.6 g Nags = 1s.sg ausoy = 12.1g. Cus produced = 3.05 g INNAS . = 78 = 0.48 78 - 0148 159.6 (Wausou / stoichiometric | WNOS l. = 15.5 = 1.28 Wh soy giren 12 Weusough | Wwas > Nags) Wasou given . (Nausoy stoichiometric that means Nags is inencess then the stoichiometric amount 4 Cusoy is pacsent is less amount then the stoichiometric amount. so ausou is limiting reagent. 159.6g of cusou produce = 95.6g of cus. lg " " " = 95.6 g of cus. 15916 19:19 " " = 95.6 x 12) = 7.2594 159.6 aus- % yield = mas obtained xio mass theoretically possible 3:05 xw = 42.069 7. 7.85
