Question

According to the bottle, a serving size of Gatorade is 240 mL. The molar mass of Red Dye #40 is 496.43 g/mol. Use this information along with the concentration of Red Dye #40 in Gatorade to calculate the mass (in mg) of Red Dye #40 ingested per serving of Gatorade.

Answer 1

Answer:

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
