Vinegar is simply a solution of acetic acid, HC2H3O2, in water. If 1.00 L of vinegar has 50.5 g of HC2H3O2 in it, what is the molar concentration of the acid in vinegar? Express your answer to three significant figures. Answer in M HC2H3O2
A student is trying to determine the concentration of an acetic acid (HC2H3O2) solution. They place 5.00 mL of it in a flask and titrate it with a 0.150 M NaOH solution. At the endpoint of the titration, they find that they have used 19.27 mL of the NaOH solution. Based on this information answer the following questions. a) How many moles of NaOH are used to reach the endpoint? ____moles NaOH b) How many moles of acetic acid were...
