Answer:

#"Concentration"# #=# #"Moles of solute"/"Volume of solution"#

Explanation:

#"Concentration"# #=# #"Moles of solute"/"Volume of solution"#

#=# #(16.7*g)/(142.04*g*mol^-1)xx1/(0.125*L)# #=# #0.940*mol*L^-1# with respect to sodium sulfate.

Note that the way we have set out the problem, appropriate units are obtained automatically. What is the concentration with respect to sulfate ion; with respect to sodium ion?
