Question
The Cu2+ ions in this experiment are produced by the reaction of 1.0 g copper turnings with excess nitric acid. How many moles of Cu2+ are produced?
Answers
moles Cu = 1g/atomic mass Cu = ??
first do gram to mole conversion
63.5g one atom of Cu...1g of Cu x 1 mole of Cu/63.5 gram of Cu = 1.6x10^-2moles cu.
1 to 1 ration, therefore, 1.6x10^-2 moles
63.5g one atom of Cu...1g of Cu x 1 mole of Cu/63.5 gram of Cu = 1.6x10^-2moles cu.
1 to 1 ration, therefore, 1.6x10^-2 moles
