Yes, dimensionless quantities are always unitless. This means they do not have any physical units associated with them, and they represent a pure numerical value that is independent of any specific unit of measurement.
No. "Dimensionless" means there are NO units involved.
No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.
Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
The index of refraction is a dimensionless quantity representing how much light bends as it passes through a medium compared to a vacuum. It is a ratio of the speed of light in a vacuum to the speed of light in the medium, so the units cancel out, leaving a unitless value.
If a quantity is "dimensionless", that means it has no units, and it's just a number.

No. "Dimensionless" means there are NO units involved.
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.

Yes. Conversion factors will generally be dimensionless constants.
The equilibrium constant is a unitless quantity.
