## Homework Statement

okay so I am going to do a lab on reaction rates, there's a table given (effects of varying concentration)

there are 9 reactions, I will just give one, ( if i can figure this out ill figure out the rest on my own)

so reaction #1 flask A contains 7.50mL of .200M KI

none of .20 M KCI

.0050 M S2O3^-2

1 drop of starch

flask B contains 7.5 mL of .100M S2O8^-2

It says for each reaction determine the concentration of KI, (NH4)2S2O8, and Na2S2O3 that will be present when solution A and B are mixed together. the total volume for each reaction is 20.0 mL.

## Homework Equations

M1V1=M2V2 ?

## The Attempt at a Solution

I'm not sure how to begin this, would I have to use the M1V1=M2V2 ? how would I set it up ?
