Record the following data in the table below Mass of Empty Beaker 185g Mass of Beaker with Silver Nitrate and Copper 391.2339 Mass of Beaker with Silver 390.233g Data Analysis 2. How many moles of silver nitrate were added to the reaction? 2 Conclusions 3. Did all the silver ions get consumed in the reaction? The molar mass of silver is 107.87 g/mol. Justify your answer A Write a halanced enuation for the reartion of AnNO-faa) with 7nfel to nrodhice Anlel and SUBMIT FOR GRADING SAVE AND FINISH LATER Discard chaExplanation / Answer
mass of beaker with silver nitrate = 391.233 g
mass of empty beaker = 185 g
The mass of silver nitrate or AgNO3 = 391.233 - 185 = 206.233 g
2. no of moles of AgNO3 = weight of AgNO3 / molar mass of AgNO3 = 206.233/ 170 = 1.213 moles
3. The amount of silver with beaker = 390.233 g
The amount of silver is = 390.233- 185 = 205.233 g
the no of moles of Ag = 205.233 / 107.87 = 1.90 moles
From the equation 2 mole of AgNO3 reacts with 1 mole of Cu, yeilds 2 moles of Ag.
From 1.21 moles of AgNO3 also yeilds 1.21 moles of Ag. And we obtained 1.9 moles because of wetness of the samples.
But overal the silver ions consumed in the reaction.
4. 2AgNO3 (aq)+ Zn (s)------> Zn(NO3)2 (aq) + 2Ag(s)
5. Mole to mole ration between Aluminum and Silver is 1:3
becausw 1 mole of Al reacts with 3 moles of AgNO3 to produce 1 mole of Al(NO3)3 and 3Ag
