Question

Given that a 20.00 g milk chocolate bar contains 12.00 g of sugar, calculate the percentage of sugar present in 20.00 g of milk chocolate bar keeping in mind that the answer should have four significant figures

Answer 1

If there is 12.00g of sugar present in a 20.00g bar of milk chocolate, 12/20 grams of the bar is sugar. We can convert 12/20 into a percentage by expressing it as a number over 100. So, we multiply both the denominator and numerator by 5 to give us 60/100. 60/100 is 60 PER CENT (meaning per 100; %), so the percentage of sugar in 20.00g of milk chocolate is 60.00%

Answer 2

Answer : The percentage of sugar present in milk chocolate bar is 60.00 %

Explanation:

We are given:

Mass of milk chocolate bar = 20.00 g

Mass of sugar = 12.00 g

To calculate the percentage of sugar present in milk chocolate bar, we use the equation:

$\text{Percentage of sugar}=\frac{\text{Mass of sugar}}{\text{Mass of milk chocolate bar}}\times 100$

Putting values in above equation, we get:

$\text{Percentage of sugar}=\frac{12.00g}{20.00g}\times 100 = 60.00\%$

Hence, the percentage of sugar present in milk chocolate bar is 60.00 %
