suppose that you have a micro pipet which delivers 100 drops per cubic centimeter, and a solution of 5.0% by volume of oil in alcohol. if you had used 10 drops of this solution, how many cubic centimeters of pure oil would be left after evaporation of the alcohol?
volume=.01cc stuff/drop * (.05concentrate)*10drops=.01*.05*10
Well, since the solution is 5.0% oil by volume, that means for every 100 drops, 5 drops are oil. So if you used 10 drops of the solution, it means you used 0.5 drops of oil.
Now, the tricky part is figuring out how to evaporate 0.5 drops of alcohol. You could try using a tiny hairdryer or asking a really tiny sun to help you out. But let's be real, even if we could evaporate that tiny amount, it's nearly impossible to measure.
So, I'm sorry to say that you won't be left with any measurable amount of pure oil after the alcohol evaporates. Looks like this microscopic oil adventure didn't quite work out. Better luck next time!
To determine the amount of pure oil left after evaporation of the alcohol, we need to first calculate the volume of the initial solution used, and then calculate the volume of oil in that solution.
Step 1: Calculate the Volume of the Initial Solution
Given:
- Number of drops: 10
- Drop volume: 1 cubic centimeter (since the pipet delivers 100 drops per cubic centimeter)
The volume of the initial solution used can be determined by dividing the number of drops by the drop volume:
Volume of solution used = Number of drops / Drop volume
Volume of solution used = 10 drops / 100 drops per cubic centimeter
Volume of solution used = 0.1 cubic centimeter
Step 2: Calculate the Volume of Oil in the Solution
Given:
- Volume percent of oil in the solution: 5.0%
The volume of oil in the solution can be calculated by multiplying the volume of the initial solution used by the volume percent of oil:
Volume of oil = Volume of solution used * Volume percent of oil
Volume of oil = 0.1 cubic centimeter * 5.0%
Volume of oil = 0.1 cubic centimeter * 0.05
Volume of oil = 0.005 cubic centimeter
Therefore, after the evaporation of the alcohol, there would be 0.005 cubic centimeters (or 5.0 microliters) of pure oil left.
To find out how many cubic centimeters of pure oil would be left after the evaporation of the alcohol, we need to calculate the volume of the oil in the 10 drops of the solution and then convert it to cubic centimeters.
First, let's determine the volume of one drop using the given information that the micro pipet delivers 100 drops per cubic centimeter. This means that each drop has a volume of 1/100 cubic centimeter.
Next, we need to calculate the volume of oil in the 10 drops. Since the solution is 5.0% by volume of oil, we can multiply the volume of the 10 drops by 5.0% to get the volume of oil.
Volume of oil = Volume of 10 drops * 5.0%
= (10 drops * 1/100 cubic centimeter per drop) * 5.0%
= (10/100) * 5.0% cubic centimeters
= 0.1 * 5.0% cubic centimeters
= 0.05 cubic centimeters
Therefore, there would be 0.05 cubic centimeters of pure oil left after the evaporation of the alcohol.
