Confirm whether sodium carbonate was in excess. Using the concentration of the sodium carbonate solution used, determine how many moles were used and confirm it was the excess reagent
only need help with "e"
1. Use the following data table and steps a-d below to calculate the concentration of the zinc carbonate. The mass of the filter paper alone (no ZnCO3) was 1.3457 g. The Zn(NO3)2 solution (10.00 mL) was mixed with 15.00 mL of the 1.00 M Na2CO3.
a. Calculate the mass of zinc carbonate formed. 0.8939
b. How many moles of zinc carbonate formed? 0.00715
c. Calculate the moles of zinc in the zinc nitrate solution
used. 0.00175
d. Calculate the concentration of the zinc in the zinc
nitrate solution. 0.715 M
e. Confirm whether sodium carbonate was in excess. Using the concentration of the sodium carbonate solution used, determine how many moles were used and confirm it was the excess reagent
