Food dye allergies have increased in recent years. One study calculated that each 47.9 g serving of M&amp;M's candy contains 240
77julia77 [94]

Answer:

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%

I will mark brainlist In what layer are convection currents found?
Pavel [41]

Answer:

Convention currents are found in the asthenosphere part present in the mantle of the Earth.

Explanation:

The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.

Beneath the Mantle lies the core which contains molten rocks and materials called magma.

The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).

As a result, large convention currents are generated excessively
