The last step is to calculate the percent by mass of each element in ammonium nitrate (NH4NO3). The masses of the elements in one mole of the compound are: mass N = 28.0 g mass H = 4.0 g mass O = 48.0 g The molar mass of the compound is 80.0 g/mol. What is the mass of one mole of the compound? 80.0g

Answer:
1. Insulin
2. Keratin
Explanation:
Proteins are one of the four biological molecules found in living systems. They are polymeric molecules made up of monomeric units called AMINO ACIDS. Proteins perform a wide variety of functions in the body ranging from enzymatic functions to structural roles.
Two examples of proteins found in the body are keratin, insulin. Keratin is a structural protein located in the skin, hair and nails while insulin is an enzymatic protein that aids in digestion.
Answer:
0.24 g
Explanation:
Given that:
The average number of the calories for the carbohydrates = 4.1 calorie / g
Also,
6 - oz serving of the diet soda contains less than 1 calorie per can
So,
Maximum mass of carbohydrate = Maximum calorie / Average number of the calories for the carbohydrates
The maximum of the calorie can be 1 calorie per can
So,
<u>Maximum mass of carbohydrate = 1 calorie / 4.1 calorie / g = 0.24 g</u>
The correct answer is (2) density.
An intensive property of a substance is a property that will never change no matter what. Density is a constant and thus an intensive property.
