<u>Answer:</u> 120 mL of ethanol must be added.
<u>Explanation:</u>
We are given:
60% ethanol by volume
This means that 60 mL of ethanol is present in 100 mL of solution
Given volume of solution = 200 mL
Applying unitary method:
If 100 mL of solution contains 60 mL of ethanol
So, 200 mL of solution will contain = of ethanol
Hence, 120 mL of ethanol must be added.

Explanation:
<em>Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.</em>
I rushed to the door to see what loud noise i heard, I seen a strange man standing on top of a body. As I screamed loudly, he started rushing towards me. ... He then began to slice my neck and I started to bleed out and collapsed on my front door. I suddenly woke up and realized it was all a dream, I went back to sleep.
It is estimated that about 1 ft of snow is equal to 1 inch of rain.
Converting inch to cm
1 inch=2.54 cm
Thus, 1 cm=0.393 inch
2.5 cm of rain will be 0.984 inch
now 1 inch of rain is equal to 1 ft of snow, thus, 0.983 inch of rain will be:
0.983 inch of rain=0.983 ft of snow.
Converting ft to cm:
1 ft =30.48 cm
Thus,
0.983 ft= 29.96 cm
Thus, 2.5 cm of rain= 29.96 cm of snow.
