Cu(s)+4HNO3(aq)→Cu(NO3)2(aq)+2NO2(g)+2H2O(l)Each student in a class placed a 2.00-gram sample of a mixture of Cu and Al in a beaker and placed the beaker in a fume hood. The students slowly poured 15.0 mL of 15.8 M HNO3(aq) into their beakers. The reaction between copper in the mixture and HNO3is depicted above.The students observed that a brown gas was released from the beakers and that solutions turned blue, indicating the formation of Cu2+. The solutions were then diluted with distilled water to known volumes. The students determined that the reaction produced 0.010 moles of Cu(NO3)2. Based on the measurement, what was the percent of Cu by mass in the original 2.00-gram sample of the mixture?A) 16%B) 32%C) 64%D) 96%
