Use a molar mass of 800g/mol for the vegetable oil and use a density of 0.88g/mL for vegetable oil and 0.79 g/mL for methanol to calculate how many moles of ethanol are used.
A 100 mL buffer solution initially has 1.00 M HClO (Ka = 3.0 × 10-8) and 0.75 M NaClO. What is the new pH when this 100 mL of 0.10 M NaOH is added to the initial buffer solution?
What is the value of the equilibrium constant for the neutralization of acetic acid with sodium hydroxide? The Ka for acetic acid is 1.8 ? 10-5 and the neutralization reaction of interest is CH3CO2H(aq) + NaOH(aq) -> H2O(l) + NaCH3CO2(aq).
If a buffer solution is 0.260M in a weak base (Kb=5.6x10^-5) and 0.550M in its conjugate acid, what is the pH.
