The mass of NH 3 produced when 131 . 8 kg of cyclohexane carbaldehyde undergoes Tollen’s test is _____ kg . (Nearest Integer) Molar mass of C = 12 g / mol N = 14 g / mol O = 16 g / mol

Step-by-step solution

RCHO + 2 Ag NH 3 2 OH → RCOONH 4 + 2 Ag + 3 NH 3 + H 2 O The RCHO is cyclohexane carbaldehyde ( C 6 H 11 CHO ). The molar mass is 112 g . The number of moles of cyclohexane carbaldehyde = 131 . 8 × 10 3 112 = 1 . 176 × 10 3   mol 1 mole of aldehyde produces 3 moles of NH 3 1 . 176 × 10 3 mol aldehyde will produce = 3 × 1 . 176 × 10 3 moles of NH 3 Mass of NH 3 produced = 3 × 1 . 176 × 10 3 × 17 = 59 . 97 × 10 3   g ≈   60   kg
