Answer:
0.3097 moles of an nonionizing solute would need to be added.
Explanation:
Molal elevation constant = 
Normal boiling point of ethanol = 
Boiling of solution =
Moles of nonionizing solute = n
Mass of ethanol (solvent) = 47.84 g
Elevation boiling point:





n = 0.3097 mol
0.3097 moles of an nonionizing solute would need to be added.

Answer:
Red, orange, yellow, green, blue, indigo, violet.
Explanation:
First you find moles of HCl.
8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl
Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
