Molarity(m)=Moles (mol) of solute/Liters (L) of solution Molarity of standard NaOH from bottle = 0.1005 M Molarity of NaOH added in titration (mL) = 10.47 mL 1. Moles of NaOH added in titration ______
The concentration of each solution will be given in molarity (M). Molarity is a quantity that expresses the moles of solute present per liter of solution. A sodium hydroxide solution is labeled as 0.1020 M. i. Write that as a ratio of moles and liters. ii. If 11.25 mL of the 0.1020 M NaOH solution is used to titrate a solution, then how many moles of NaOH does that represent? iii. If the number of moles of unknown acid neutralized are determined to...
