In a laboratory experiment, 27.5 g of Cu were reacted with 125 g of HNO3 (63.01 g/mol):
3 Cu + 8 HNO 3 Cu(NO3)2 + 4H2O + 2 NO
a. How many grams of Cu(NO3)2 (187.57 g/mol) can be theoretically produced?
b. How many grams of excess reactant remain?
c. If the percent yield of Cu(NO3)2 is 87.3%, what is the actual yield in grams?

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
