The quantity of required dry solute is <u>4.1g KCl for 107 g of 0.535m soln.</u>

<u>Explanation:</u>

<u> Given:</u>

MM of KCl is 74.55

107g of 0.535m KCl

0.535 molal = 0.535 mols KCl/kg solvent.

0.535 mols KCl = 74.55 x 0.535

                          = 39.88 g KCl.

Therefore a 0.535 m soln consists of 39.88 g KCl + 1000 g H2O for a total of 1039.88 g solution.

To get 107 g of solution

39.88 x (107/1038.88) = 4.1g KCl for 107 g of 0.535m soln.  

The quantity of required dry solute is 4.1g KCl for 107 g of 0.535m soln.

One of the problems faced by farmers in the late 1800s was that railroads
NNADVOKAT [17]
 ...Charged very high prices to move farm products to market 
The farmers felt the railroads had monopoly power over them. The farmers essentially had no choice but to send their crops to market on trains. There was not much, if any, competition on most short-line tracks that went through farm areas. Therefore, most farmers had to simply accept whatever price railroads charged to transport crops. Farmers felt the railroads could gouge them by charging high prices and that they, the farmers, had no recourse when this happened. They blamed much of their trouble on this monopoly power.
