What is my theoretical yield of sodium oxide if I start with 20 grams calcium oxide in the reaction #2NaCl + CaO -> CaCl_2 + Na_2O#?

Approx. 20 g of #Na_2O# could be isolated.

Explanation:

#2NaCl + CaO rarr CaCl_2 + Na_2O#

#"Moles of calcium oxide"# #=# #(20*g)/(56.08*g*mol^-1)=0.357*mol.#

Given the stoichiometric equation, which you have kindly provided, clearly, at most, I can get an equivalent quantity of #"natrium oxide"#.

And thus we multiply the molar quantity by the molar mass of natrium oxide to get:

#0.357*molxx61.98*g*mol^-1=??g#
