(i)what mass of carbon dioxide (in kg) is produced upon the complete combustion of
18.9 l of propane (approximate contents of one 5-gallon tank)? assume that the
density of the liquid propane in the tank is 0.621 g/ml . (hint: begin by writing
a balanced equation for the combustion reaction.)
m=? kg
(ii) a 22.0 - ml sample of an unknown h3po4 solution is titrated with a 0.110 m naoh
solution. the equivalence point is reached when 18.60 ml of naoh solution is added.
what is the concentration of the unknown h3po4 solution? the neutralization reaction is as
follows:
h3po4(aq) + 3naoh(aq) > 3h2o(l) + na3po4(aq)
m=?
