if 2x10^-4 mol of S2O8 2- in 50 mL of solution is consumed in 188 seconds, what is the rate of consumption of S2O8 2- ?

Rate is in units of molarity per second, M/s or M sâ€?.  Since molarity is moles per liter, mol/L or mol Lâ€?, the units of the rate are mol Lâ€? sâ€?,
 
    mol   
    L s
 
Just plug in your number of moles, volume (convert to liters), and seconds, and that will give you the rate in M/s.
