Answer: 
formula units
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of 
contains of formula units
Thus 0.203 mole of contains =
of formula units
Steel is an alloy that is mainly comprised of CARBON. Hope this helps and give thanks plsss!
Answer:....................................
Explanation:
We can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.
<h3>What are these bases in DNA?</h3>
The AGCT bases in DNA are the nucleotides that comprise it. These nucleotides include
- Adenine
- Cytosine
- Guanine
- Thymine
By always bonding adenines with thymine and Guanine with cytosines, the DNA strand maintains a constant diameter.
Therefore, we can confirm that the diameter of the double helix structure of DNA stays the same because hydrogen bonding is always between the A and T bases and the G and C bases.
