Respuesta :

The answer is that KHC8H404 reacts with NaOH in an acid-base reaction to produce the salt NaKC8H404 and H20.

NaKC6H4O4 + H2O from KHISHIOI - NAOH

Therefore, for a full reaction, the moles of KHCBH404 and NaOH should be identical. The KHC8H404 moles KHC8H404 molecular mass as a function of mass

KHC8H4041.0236 gram in mass

KHC8H4041.0236/204.22 moles, weighing 204.22-gram moles.

KHC8H404 has a molar mass of=

Molarity Volume = Mole of NaOH (L)

Initial burette minus the final burette measurement Equals volume of NaOH

=13.81 ml 13.81/1000 L

Molarity (13.81/1000) moles = moles of NaOH Mole of KHC8H404 = Mole of NaOH

M (13.81/1000)=10236/204.22

M = 1.0236 (20.22, 14.22, 13.81, 1000) moles/L

M=0.3629 moles/liter G

What is Molarity?

  • Molarity is also known as a concentration in terms of quantity, molarity, or substance.
  • It is a way to gauge how much of a certain chemical species—in this case, a solute—is present in a solution.
  • It is a material per unit volume of solution in terms of quantity.
  • The number of moles per liter is the molarity unit that is most frequently used in chemistry.
  • One mol/L of a solution's concentration is referred to as its molarity. It is frequently abbreviated as 1 M.
