To find the length of the protein molecule, we multiply the diameter of a hydrogen atom by 2000 (which is
).
The calculation looks like this:
When we compute this, we first multiply the coefficients:
Next, we add the exponents of 10:
Putting it all together, we get:
So the answer is
meters.
Did you know that the sizes of atoms and molecules are typically measured in picometers (10^-12 meters) or nanometers (10^-9 meters) because they are so small? The hydrogen atom’s size gives us a peek into the atomic world, where size is minuscule but crucial for understanding chemical reactions!
For more trivia, it’s interesting to note that proteins, made up of long chains of amino acids, are vital for life. Their functions range from catalyzing metabolic reactions to replicating DNA. Scientists constantly study their structure and interactions to better understand biology and develop medicines!
