It was determined by spectrophotometry that the moles of FESCN2+ equilibrium was 2.00 x 104 moles (2.00 times 10 to the minus 4th power moles). If the sample was prepared using 4.00 x 103 moles (4.00 times 10 to the minus 3rd power moles) of Fes, how many moles of Fe3+ present at were present at equilibrium?

Question
Transcribed Image Text:It was determined by spectrophotometry that the moles of FeSCN2+ present at
equilibrium was 2.00 x 10-4 moles (2.00 times 10 to the minus 4th power moles). If
the sample was prepared using 4.00 x 103 moles (4.00 times 10 to the minus 3rd
power moles) of Fe3+, how many moles of Fe3+ were present at equilibrium?
4.00 x 10-3 moles (4.00 times 10 to the minus 3rd power moles).
O 3.8 x 103 moles (3.8 times 10 to the minus 3rd power moles)
O 2.00 x 10-3 moles (2.00 times 10 to the minus 3rd power moles)
O 4.2 x 10-4 moles (4.2 times 10 to the minus 4th power moles)
O 4.00 x 10-4 moles (4.00 times 10 to the minus 4th power moles)
