Many metals react with oxygen gas to form the metal oxide. For
example, calcium reacts as follows: 2Ca(s) +O2 (g) →2CaO(s) [molar
mass of Ca = 40 g/mol] You wish to calculate the mass (g) of
calcium oxide that can be prepared from 4.20 g of Ca and 2.80 g of
O2.
(a) What amount (mol) of CaO can be produced from the given mass
of Ca?
(b) What amount (mol) of CaO can be produced from the given mass
of O2?
(c) Which is the limiting reactant?
(d) How many grams of CaO can be produced?
