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.
Answer: African Americans didn't continue these jobs because...
1. Their bosses fired them, because they too, didn't have much money to spend
2. Their bosses fired them and replaced them with jobless white people. They did this because many white people still believed that African Americans weren't as good and they would rather give their "good fellow citizens" the job instead
I hope this helped! :)
