(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You prepare your standardization solution by weighing out 0.0750 grams of standard ascorbic acid (176.12 g/mol) and dissolving it in 50.00 mL of water. You then add ten drops of starch indicator. How many milliliters of 0.015M triiodide solution will you need to reach the endpoint of the titration?

2. Relevant equations

M1V1=M2V2

3. The attempt at a solution

[(0.0750 g X 176.12 g/mol) / (50 mL water) V1]= [(0.015 M) (V2)]

How do I solve this, seeing as I have 2 unknowns (V1 and V2)? Am I doing it wrong?
