The correct answer is option B.
The liquid or gas that carries the sample across the solid support is called mobile phase.
In chromatography, there are two phases: mobile phase and solid phase.
The mobile phase can be either in gas form or liquid form.
While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.
In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.
on the other hand, stationary phase is motionless.

<u>Answer:</u> The density of liquid is 
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 65.1 g
Mass of liquid and cylinder combined, M = 120.5 g
Mass of liquid,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of liquid = 55.4 g
Volume of liquid = 49.3 mL =
(Conversion factor:
)
Putting values in above equation, we get:

Hence, the density of liquid is 
Answer:
Believe it or not our the light we see "visible light" is an example of electromagnetic wave. other examples include microwaves, radio waves, infrared, ultraviolet, x-rays, and gamma rays.
Explanation:
Answer:
183 cg = 0.00183 kg
0.25 kg = 250 g
Explanation:
Use conversion factors. 1kg is equal to 1 x 10^5 cg (100000) and 1 kg is equal to 1 x 10^3 grams (1000 grams).
