A combustion analysis of a 0.44g sample of an unknown compound
yields 0.88 g CO2 and 0.36 g H2O. If the sample a molar mass of 132
g/mol, what is the molecular formula of the sample?
Complete combustion of 7.60 g of a hydrocarbon produced 23.0 g
of CO2 and 11.8 g of H2O. What is the empirical formula for the
hydrocarbon? I got C4H10 but was incorrect.
Complete combustion of 7.70 g of a hydrocarbon produced 23.6 g
of CO2 and 11.3 g of H2O. What is the empirical formula for the
hydrocarbon? Insert the subscripts:
CH
Hydrocarbon mixtures are used as fuels. How many grams
of CO2(g) are
produced by the combustion of 574 g of a mixture that is
31.6% CH4 and
68.4% C3H8 by
mass?
___ × 10____
g
