Manipulate: Recall that molarity is equal to the number of moles of a substance dissolved in one liter of solution: molarity = moles ÷ volume. A. Write an equation for determining the number of moles of NaOH that are added to the flask based on [NaOH] and volume of NaOH titrant (mL NaOH):

Moles NaOH =

B. Write a similar expression for the number of moles of H2SO4 in the flask based on [H2SO4] and the volume of H2SO4 (mL).

Moles H2SO4 =

C. Because there are twice as many moles of NaOH as moles of H2SO4 in this reaction, you can say:

Moles NaOH = 2 · Moles H2SO4

Substitute your expressions from 3A and 3B into this equation and solve for [H2SO4]:

D. Now calculate [H2SO4] based on the data from the Gizmo. [H2SO4] = ___________
