Question
Exercise 13.80 Part A Determine the concentration of the cation and anion in each aqueous solution. (Assume complete dissociation of each compound.) 0.70 MSrSO4 Express your answer using two significant figures.

Enter your answers numerically separated by a comma Submit My Answers Give Up Part C 0.30 M Srl2 Express your answer using two significant figures. Enter your answers numerically separated by a comma Sr2 +,1 =Explanation / Answer
A)
[Sr+2] = [SrSO4]
= 0.70 M
[SO4-2] = [SrSO4]
= 0.70 M
B)
[Cr+3] = 2*[Cr2(SO4)3]
= 2*0.15
= 0.30 M
[SO4-2] = 3*[Cr2(SO4)3]
= 3*0.15
= 0.45 M
C)
[Sr+2] = [SrI2]
= 0.30 M
[I-] = 2*[SrI2]
= 2*0.30
= 0.60 M
