Chemical analysis of an unknown compound gives a molarmass of
334 g/mol and a percentage composition of 75.42% carbon,6.63% hydrogen,
8.38% nitrogen, and the rest is oxygen. Calculate theempirical and molecular
formulas for the unknown compound.
2.) Write a balanced chemical equation for the completecombustion of
pentane (C5H12). If 100.00 g of pentane are combusted inexcess O2, what mass
of CO2 would be released to the atmosphere?
