Answer to Question #15659 in Organic Chemistry for Ting
When 1.0000g of a compound containing C, H, and N is combusted, 2.6667 g of CO2 and 5455g of H2o is produced...
a) determine the g of C in this compound
b) determine the g of H in this compound
c) determine the g of N in this compound
d)determine the empirical and the molecular formula of this compound
The compound has formula C(x)H(y)N(z). The combustion reaction is C(x)H(y)N(z) + O2 = xCO2 + (y/2)H2O + (z/2)N2 x to y ratio is (2.6667/44):(2*0.5455/18)= 0.06061/0.06061=1 : 1 Thus, the compound formula is CHN(z). The Molecular mass of the compound is (12 + 1 + 14z) For x=1, the empirical formula is CHN4. The molecular formula is C2H2N8 - 5,5'-bistetrazole.
