Ammonium nitrate decomposes (explosively) according to the following reaction.

2NH4NO3 " src="http://loncapa.net/res/sfu/batchelo/Gallery/rarrow.gif" align="middle"> 2N2 + O2 + 4H2O
What mass of H2O can be formed from the decomposition of 16.9 g of NH4NO3?

2NH4NO3 --> 2N2 + O2 + 4H2O

Mol. wt NH4NO3 = 80.0434 g/mol

Mol. wt N2 = 28 g/mol

Mol. wt O2 = 32 g/mol

Mol. wt H2O = 18 g/mol

16.9 g of  NH4NO3 = 0.211 mol

So, with decomposition of 0.211 mol of NH4NO3 , 4*0.211 moles of H2O are formed

H2O formed = 0.844 mols = 0.844 * 18 g = 15.201 gms

Sorry my bad.....

Answer is 2*0.211 = 0.422moles = 7.6 gms...
