In a particular reaction between copper metal and silver nitrate, 12.7 g AgNO3 produced 4.57 g Ag. What is the percent yield of silver in this reaction??

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
