a. You are provided with a 250 mL volumetric flask, deionized water, and solid NaOH. How much NaOH should be weighed out in order to make 250. mL of 0.100 M solution?
b. 25.0 mL of the 0.100 M aqueous NaOH is titrated against sulfuric acid, H2SO4, according to the equation
2NaOH(aq) + H2SO4(aq) Na2SO4(aq) + 2H2O(l)
If the volume of sulfuric acid solution required to neutralize the NaOH is 18.62 mL, what is its concentration?
