The YBa2Cu3O7 superconductor can be synthesized by the
sol–gel method from a stoichiometric mixture of metal ethoxides
followed by heating in oxygen. How many grams of
Y1OCH2CH323 and how many grams of Ba1OCH2CH322
are required to react with 75.4 g of Cu1OCH2CH322 and
an excess of water? Assuming a 100% yield, how many
grams of YBa2Cu3O7 are obtained?
