A student wants to prepare 400 mL of buffer with a pH of 4.90 using acetic acid and sodium acetate. a) What should be the acid-salt molar ratio for the buffer? b) If he prepares the solution at a HOAc concentration of 0.12M, how many grams of NaOAc must he add to obtain the desired pH?

The correct answer is: The map illustrates the size of the Louisiana Purchase and suggests its economic potential.

Indeed, since the map does not have any highlighted areas that show the extent of sugar plantations, it can only be deducted that it only shows the economic potential of the territory by showing how so much of it is located within the warm, Sun Belt of the United States where the climate is favorable for the cultivation of sugar (especially the humid areas of Southern Louisiana and Texas.

After the Haitian revolution and its horrors, many free colored Haitians (and some white Haitians) escaped to the United States and started large sugar plantations since most sugar plantations in Haiti were devastated and never recovered.
