Density and Refractive Index for a Diatrizoate Sodium Gradient

 

Molecular weight of diatrizoate sodium: 635.9

 

Parameter: aqueous diatrizoate sodium solution as percent weight by weight, as a decimal fraction from 0 to 0.40.

 

percent weight by weight as decimal fraction =

= (grams of solute) / (total weight of solution)

 

density of a diatrizoate sodium solution at a given percent (weight for weight) as a decimal fraction =

= (0.6227 * ((percent)^2)) + (0.5775 * (percent)) + 0.9989

 

refractive index of a diatrizoate sodium solution at a given percent (weight for weight) as a decimal fraction =

= (0.214 * ((percent)^3)) + (0.03009 * ((percent)^2)) + (0.1625 * (percent)) +1.333
