Question

Answer 1

Answer:

0.03 grams

Step-by-step explanation:

Given:

An aerogel meringue weighs 1.17 grams

It is 96% air and 1.3 egg whites.

The rest is sugar.

To find:

How much sugar is in the meringue, rounded to the nearest hundredth?

Solution:

An aerogel meringue weighs = 1.17 grams

Percentage of air = 96%

Percentage of egg whites = 1.3%

Now, to find first of all to find the percentage of sugar, we will add the percentage of air with the percentage of egg whites,

96% + 1.3% = 97.3%

As here given that the remaining percentage is sugar therefore,

100% - 97.3% = 2.7%

Now, to find the quantity of sugar in meringue,

$2.7\% \ of 1.17 gram =\frac{2.7}{100} \times1.17 = \frac{3.159}{100} =0.0315 \ grams$

Therefore, sugar is 0.03 grams in the meringue.
