I assume you are referring to Retention Factor and have been doing some chromatography. There's a few things that could take the initials RF so if you mean something else, just ask again with more specifics.
That said, there are no units to retention factor. It's a ratio. Pure ratios should never have units.
We can see this with a little mathematical proof.
rf value is calculated by dividing the distance your solvent travelled to the distance your compound travelled (always this way round. You should always get an answer between 0 and 1. if you don't, you've done it wrong).
So it's like saying cm/cm, which we can see works out unitless.

What is the full name of Rf value?
Retention Factor Rf == Distance traveled / total distance
Difference Rf values for monosaccarides and disaccharides?
Monosaccharides generally have lower Rf values compared to disaccharides because they are smaller molecules and tend to move less on the chromatography paper. Disaccharides are larger molecules composed of two monosaccharide units, so they tend to have higher Rf values due to their increased size.
What do the Rf values indicate about the relative solubility of the pigment in the the solvent?
The Rf value indicates the ratio of the distance a pigment travels compared to the distance the solvent travels on a chromatography plate. The higher the Rf value, the more soluble the pigment is in the solvent used for the chromatography.
What is the maximum and RF value can be?
The maximum RF value that can be obtained is 1.0. This means that the substance travels the full distance of the chromatography medium being used. Any RF value greater than 1 is not physically possible.
How does saturation effect RF value?
In general, as saturation increases, the RF value decreases. This is because an increase in saturation tends to increase retention of the compound on the stationary phase, resulting in a lower RF value. Conversely, lower saturation levels may allow the compound to move more freely, leading to a higher RF value.
What is the unit of rf?
there are no units... it is a ratio.
What is Rf-value Why its has no unit?
There are no units because it is simply a ratio
What is the full name of Rf value?
Retention Factor Rf == Distance traveled / total distance
How do you calculate RF Value?
RF value is calculated by dividing the distance traveled by the compound by the distance traveled by the solvent in a chromatography experiment. It is a ratio and has no units. The RF value is a useful tool for identifying compounds and is unique to each compound.
What is a rf scale?
A RF scale is a measurement scale used in radio frequency technology to quantify signal strength and power levels. It is typically used to determine the strength of a radio signal in decibels (dB) relative to a reference level. A higher RF scale value indicates a stronger signal, while a lower value indicates a weaker signal.

What is the rf value of cocaine?

What do you mean rf cable?
RF = Radio Frequency
Find the risk-free rate given that the expected rate of return on asset j is 14 percent the expected return on the market portfolio is 12 percent and the beta b for asset j is 1.5?
CAPM equation E(Rj) = rf + b[E(Rm) - rf] 0.14 = rf + 1.5(0.12-rf) 0.14 = rf + 0.18 - 1.5rf -0.04 = rf - 1.5rf -0.04 = (1-1.5)rf -0.04 = -0.5rf rf = 0.08 rf = 8%
