Answer:
9.2 grams of ethanol should be added.
Explanation:
Let the mass of ethanol be x
Density of an ethanol = 
Volume of the ethanol =
Mass of chloroform = 5.0 g
Density of an chloroform= 
Volume of the ethanol =
Mass of the mixture,m = x + 5.0 g
Density of the mixture = 
Volume of the mixture=



Solving for x , we get
x = 9.2 g
9.2 grams of ethanol should be added.
