Question
100%
My experiment was to have eight drops of liquid in each well. For a one I had five drops of Na2S2O3 and three drops of hydrochloric acid. For well A2 I had four drops of Na2S2O3, One drop of distilled water, and three drops of hydrochloric acid. For well a three I had three drops of Na2S2O3, two drops of distilled water, and three drops of hydrochloric acid. Four well a four I had two drops of Na2S2O3, three drops of distilled water, and three drops of hydrochloric acid. Use the table for information to answer the questions below. Additional information: hydrochloric acid = 0.1M and the sodium Thiosulfate (Na2S2O3) = 0.1M.
I already have the information for 1-3 including the table filled out and graph (included if needed). The main questions I need help with is #4-6

1. Each well has 8 drops of liquid. Use the formula M,V, M,V, to calculate the molarity
of the Na S,O, in each well. For more information about this formula, read the
