RCHO + 2 [Ag (NH 3 ) 2 ] OH 
RCOONH 4 + 2Ag + 3 NH 3 + H 2 O
The RCHO is cyclohexane carbaldehyde (C 6 H 11 CHO). The molar mass is l12g.
The number of moles of cyclohexane carbaldehyde= 
= 1.176 x 10 3 mol
1 mole of aldehyde produces 3 moles of NH 3
1.176 x 10 3 mol aldehyde will produce
= 3 x 1.176 x 10 3 moles of NH 3
Mass of NH 3 produced = 3 x 1.176 x 10 3 x 17
= 59.97 x 10 3 g
60kg
