Answer 1

2 mole weight N2 + 3H2 = 2 NH3 1 mole - 3 mole 10.2 g 10 63g 1.099 1029 10629 * No. of moles - 2 g/mole • Gram Molecules wought 0.364 mole Orginale Actually 'He should be a times to the moles of 'Ne (ie) (3 +0.3647 molez 1. = 1.092-mides But ty has 0.81 moles (lesser than 1.092 moles) .. Limiting reagent is 'ha Here Lesser noo of moles reactant be considered as Limiting ruagant 3 mol H2 - 2 mole NH3 0.81 mol H₂ - ? 0.8l mole x 2 wide a 3 mole = 0.54 mile NH3 0.54-mole NH3 weight = 0.54 mole x Game of NH3 = 0.54. moltex 17 g mre = 9.19 g 7 yild of NH₃ = given weight - x 100 Calculated weight = 1:09 9 x 100 9.18 g 211.87.6. to yield of NH3 = 11.9
