An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in
an excess of O2(g) and yields 0.347 g CO2(g) (carbon
dioxide).
Set up two algebraic equations, one expressing the mass of carbon
dioxide produced in terms of each reagent and the other expressing
the mass of sample burned in terms of each reagent.
What is the mass of methyl alcohol (CH3OH) in the sample?

A 384.0 g/hr stream of liquid methyl alcohol, also called
methanol, (CH3OH) at 7.60 atm and 10.0°C was held at
constant pressure, vaporized and brought to 564.0°C. At what rate
must heat be supplied to this system? Assume that methyl alcohol
vapor behaves ideally for the temperature range and pressure
given.

A 5 g mixture of ethanol (C2H5OH) and
methanol (CH3OH) reacts with excess oxygen. If this
combustion releases 125.46 kJ of heat, what mass of ethanol is in
the mixture? Assume that mixing does not affect any enthalpy
values.

The formation of ethyl alcohol (C2H5OH MM
= 46.08 g/mol) by the fermentation of glucose
(C6H12O6 MM = 180.18 g/mol) may be
represented by:
C6H12O6 →
2C2H5OH + 2CO2
