Answer 1

Mole concept.

(13 Given equation 4NH3 +702 ca] 4NO2(g) + 6H₂O (9) (9) 7 more umoce 6 moles According mole umole concept i u mole of NH₃ requird to produces - 6 moles of H₂O → 6.moles of Ho ? Say (x). E & 1015 mol of H2o u moles of NH3 10.5 mole x u mole x x 6 indle = - 1005 mole x 4 mole . 6 niple 42 mole . .. 6 x= 7 mole 7:00 mole of NH₃ requird to producers . 10.5 mole of H₂O i key © is correct auswer
