A method for producing pure copper metal involves the reaction of copper(I)sulfide with oxygen gas to give copper metal and sulfur dioxide. Suppose the yield of this reaction is 87%.What mass of a copper ore consisting of 46% copper(I)sulfide must be mined in order to produce 1.0 *10³ kg (1.0 metric ton)of copper metal? A)1.4 * 10³ kg B)3.2 * 10³ kg C)1.3 * 10³ kg D)1.5 * 10³ kg E)8.0 * 10³ kg

To produce 1.0 * 10^3 kg of copper with an 87% yield, you need more copper(I) sulfide than the theoretical amount. The ore is 46% copper(I) sulfide, so you need to mine approximately 3.2 * 10^3 kg of ore to account for the yield and purity.
