Question

What is the concentration of each ion in 15.00 ml of a 7.85 X 10^-6 M solution of Tc3 (PO4)7?

Answer 1

Tc^(+7) - 2.35*10^-5M

PO4(^-3) - 5.50*10^-5M

Step-by-step explanation:

Tc3(PO4)7 <--->
`3Tc^(7+) + 7PO_(4)^(3-)`

1 mol 3 mol 7 mol

7.85 X 10^-6 M 3*7.85*10^-6M 7*7.85*10^-6M

2.35*10^-5M 5.50*10^-5M
