how many milliliters of .242 m of NaOH are required to exactly titrate 18.0 grams of H2C2O4

Answer 1

Since you are using text style typing, I wonder if that is 0.242 m or 0.242 M. It makes a difference. I think you probably meant for it to be M.
If so then use mL x M = mL x M.
If actually m, then convert m to M and use the above formula.
