Shelton · Answer 1

mass Red Dye 40 = 0.0696 mg

Explanation:

aas found by means of quantitative methods of analysis of dyes in sports drinks:

⇒ [Red Dze 40] = 5.842 E-7 mol/L

analysis performed at a wavelength of 504 nm; value that is below the allowable limits for these drinks.

∴ mass of Red Dye ingested:

⇒ mass Red Dye = (5.842 E-7 mol/L) (496.43 g/mol) (1000 mg/g) (0.240 L)

⇒ mass Red Dye = 0.0696 mg
