Empirical measurement of the density (g/ml) of fructose, glucose, and sucrose solutions.

Fructose = Sigma F0127, MW 180
Glucose = Sigma G8270, MW 180
Sucrose = JT Baker 4097-06, MW 342
Note that sucrose is a disaccharide with almost 2x the MW of fructose and glucose; thus 1 M fructose = 180 g/L, while 1 M sucrose = 342 g/L.
Mixed in house distilled water, brought to 1 Liter in volumetric flask.
