Reline osmotic pressure vs. molality at 25 degrees Celsius
Reline is defined as two urea and one choline chloride molecules. When mixed together at this 2:1 (urea:cholinechloride mole ratio) ratio, they form a deep eutectic solvent, termed Reline.

The data set is adequately captured by the following cubic term:
Osmolal = 0.00023*m^3 - 0.04598*m^2 + 3.75984*m
