Explanation:
It is recommended only for the second type of candy to be taken off the market.
Based on the background information, if a candy shows a 0,62 Rf value in the chromatography it is considered potentially dangerous, and therefore it should be taken off the market.
The Rf value is calculated using the following formula:
- Rf = Total distance traveled by a component/ Total distance from the pencil line to the solvent front
Now, let's find out if any of the components has an Rf equal to 0,62.
Note: To determine the distances I measured the image using a ruler and you can do the same, this will not alter the results.
- Sample 1
- Total distance traveled by the component: 6cm
- Total distance: 7 cm
- Rf : 6 cm/ 7 cm = 0.85
2. Sample 2
- Total distance traveled by the component: 4.34cm
- Total distance: 7 cm
- Rf : 4.34 cm/ 7 cm = 0.62
This means sample 2 has the 0.62 Rf value and therefore it needs to be taken off the market.

Answer:
Explanation:
Volume of vodka = 9.62 - 1.52 = 8.10 mL drained into beaker .
Mass of vodka drained out = 21.123 - 13.687 = 7.436 g
density of vodka = mass / volume
= 7.436 / 8.10 g / mL .
.918 g / mL .
