Help! I'm not quite sure how I should set up this experiment (as in how much I should weigh of the dry powder, etc) The question asks: " Given the materials list below and Table 2, design a procedure to make the three stock solutions in sufficient amounts to complete the experiment with minimal waste. Solutions: 0.10 M ascorbic acid, 4.0x10-4 M methylene blue, 1.20 M HCl Materials: Ascorbic acid (dry powder); methylene blue (supplied as a hydrated chloride salt—3,7-bis(dimethylamino)phenazathionium...

I'm doing a titration lab tomorrow and I am not sure what the
formulas are to calculate the moles of NaOH, the moles of
HCl, and the molarity of HCl.
The objective of this laboratory is to determine the molarity of
a hydrochloric acid solution using a known concentration of sodium
hydroxide as the titrant.
volume of HCl in flask: 25.00 mL
the net ionic equation for the reaction is:
H+(aq) + OH-(aq) --> H2O(l)
