Why concentrated HNO3 is 69% by mass of nitric acid? Please explain what it means.
Lyrx [107]

Answer:

See the answer below

Explanation:

<u>The percentage by mass of a substance in a mixture is the ratio of the mass of the substance and the mass of the entire mixture.</u>

How is it possible to have thousands of different proteins when there are only 20 different amino acids?
STatiana [176]
Hi there!

Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins. 

In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.
