Question

A 12.00 g milk chocolate bar is found to contain 8.000 g of sugar. What will be the amount of sugar in milligrams if the size of the milk chocolate bar is reduced from 12.00 g to 5.000 g ?

Answer 1

Answer:

3,333.33 will be the amount of sugar in milligrams.

Explanation:

Amount of sugar in 12.00 g of milk chocolate bar = 8.000 g

Amount of sugar in 1 g of milk chocolate bar = $\frac{8.000 g}{12.00 g}$

Amount of sugar in 5.000 of milk chocolate bar :

$\frac{8.000 g}{12.00 g}\times 5.000 g= 3.33333 g$

1 g = 1000 mg

3.33333 g = 3,333.33 mg

Answer 2

Answer is: amount of sugar in milk chocolade is 3333 mg.
To solve this question, make proportion: if 12,00 grams of milk chocolate contain 8,00 grams of sugar, than 5,00 grams contain:
12,000 g : 8,000 g = 5,000 g : m(sugar).
12,000 g · m(sugar) = 8,000 g · 5,000 g.
m(sugar) = 40,000 ÷ 12,000.
m(sugar) = 3,333 g = 3333 mg.
