I have to calculate the concentration of I2 produced (# of moles of I2 produced / L) based on the stoichiometric ratio in the following equation.
2S2O3^2 + I2 > 2I^ + S4O6^2

If you know the number of moles of S2O3^2 then the number of mols I2 will be 1/2 that. I suspect you have M and L of S2O3^ and M x L = moles S2O3^2.

moles = M x L
M is the concentration correct?

Amanda Mosley
Yes m is

Hannah
Is L just the unit? Moles would be 3.33e3M / L ?

Amanda Mosley
Yes u remember where it says mxL this means that your multiplying m by l and l would be the unit

Hannah
So to find the amount of I2 produced as I first posted, it would be 1/2 that of 3.33e3 correct? So 0.0666? Sorry, its important that I understand this correct

Amanda Mosley
Yes i tried your question and this is what i received

Hannah
So the answer would be 6.66e2 L*min? Is that the correct unit?

Hannah
Sorry I actually got 0.00666 so it would be 6.6e3 correct?

Hannah
So I got 6.6e3 L*min for the amount of I2 produced. Now I have to calculate the rate for each of the 5 flasks used, so is the answer going to be the same for all 5?? It says to calculate the rate of reaction for each run using # of moles of I2 produced/L*min as the unit.
