Food dye allergies have increased in recent years. One study calculated that each 47.9 g serving of M&M's candy contains 240 calories 10 g of fat, 34 g of carbohydrates , 2 g of proteinand 29.5 mg of food dyes. What is the mass percent of food dyes in the M &M's candy ?
A ) 0.0616%
B) 4.18%
C)20.9
D) 71.5 %

Mass percent of food dyes  = 0.0616%

Explanation:

Given data:

Mass of candy = 47.9 g

Calories = 240

Mass of fat = 10 g

Mass of carbohydrate = 34 g

Mass of protein = 2 g

Mass of food dyes = 29.5 mg

Mass percent of food dyes = ?

Solution:

First of all we will convert the mg into g.

Mass of food dyes = 29.5 mg × 1g /1000 mg = 0.0295 g

Mass percent of food dyes  = mass of food dyes / total mass× 100

Now we will put the values.

Mass percent of food dyes  = 0.0295 g / 47.9 g × 100

Mass percent of food dyes  =  0.000616 × 100

Mass percent of food dyes  = 0.0616%
