A)93

Multiple Choice

A copper ore consisting of 12.5% copper(II) sulfide 95.61 g/mol) , when heated and reacted with oxygen gas 32.00 g/mol) , produces copper(II) oxide (79.55 g/mol) and sulfur dioxide (64.06 g/mol) .If the reaction has a 90.0% yield, how many grams of copperII) oxide are produced when 1.00 kg of the copper ore is processed?
