Assume that the buret below was previously filled to the 0.00 mL mark. What volume of reagent has been delivered? (Remember to estimate between the lines to get one more digit than can be read from the scale and include units!) 1

I need help calculating the "titre" for both trials please (shown in the first picture).

POSTLABORATORY ASSIGNMENT 1. An oleic acid, C17H33COOH (282 g/mol), solution is added to water in a watchglass until a monolayer forms. Assume that there are no spaces between molecules in the monolayer and that each oleic acid molecule occupies an area of 0.25 nm². If the concentration of the oleic acid solution is 0.00012 g/mL, what is the experimental value of Avogadro's number? dropper pipet calibration number of drops of oleic acid in the monolayer diameter of monolayer OMA 30+20 od os pulgad Im od of ingranit yd souls mesto bonstantial = || || || 00.1 arestusslom (0) N = = = Jorna ode 65 drops/mL 16 drops 14.5 cm dirua orli unalools) mano lo zemoristalls d A(otho) wall

Here is a graph of the molarity of ethanol C2H5OH in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below.
