Asked by Beth
Ammonia gas and carbon dioxide gas react to form aqueous urea (NH2CoNH2) and water. What volume of ammonia at 25 degrees celcius and 1.5 atm pressure is needed to produce 500 g of urea?

R.
PV = nRT where R = 0.0821 atm.L / K.mol
NH2CONH2 = (14.01)(2)+(1.01)(4)+(12.01)+(16) = 60.07
n = 500 g/60.07 g = 8.32362244049 = 8.3236 mol of NH2CONH2 = 16.6472 mol of NH3
(1.5)V = (16.6472)(0.0821 atm L / K mol)(298.15 K)
(1.5)V = 407.492076028
V = 271.661384019
271.66 L of ammonia gas
