Answer:

see below

Explanation:

moles H₂A in soln = moles NaOH used in titration

moles = Molarity x Volume in Liters

moles H₂A = moles NaOH used = (0.100M)(0.02258L) = 0.0023 mol H₂A

Answer:

0.0023 moles of H₂A

Explanation:

moles H₂A in soln = moles NaOH used in titration

moles = Molarity x Volume in Liters

moles H₂A = moles NaOH used

Which is = (0.100M)(0.02258L) = 0.0023 mol H₂A
