Life processes depend in large part on solutions. Oxygen from the lungs goes into solution in the blood plasma, unites chemically with the hemoglobin in the red blood cells, and is released to the body tissues. The products of digestion also are carried in solution to the different parts of the body. The ability of liquids to dissolve other fluids or solids has many practical applications. Chemists take advantage of differences in solubility to separate and purify materials and to carry out chemical analysis. Most chemical reactions occur in solution and are influenced by the solubilities of the reagents. Materials for chemical manufacturing equipment are selected to resist the solvent action of their contents.
Answer:
<u>b. 22%</u>
Explanation:
In order to calculate the percent of calories coming from sugar, it is necessary to know that
- <u>1 g of sugar provides 4 calories.</u>
It is provided in the question that,
- There are <u>13 grams of sugar in one serving of granola cereal box.</u>
- There are <u>240 calories in one serving of granola cereal box</u>.
Calculating the calories coming from sugar,
<u>13 x 4= 52 calories</u>
Hence, calculating the percent of calories coming from sugar,
x100 = 21.6% approximated to 22%
<u>Therefore, 22% of calories come from sugar in a serving of granola cereal box.</u>
