"How many formula units are there in sample of copper(II) sulfate that has
babymother [125]

Answer: 1.23\times 10^{23} formula units

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{32.5g}{160g/mol}=0.203moles

1 mole of CuSO_4 contains 6.023\times 10^{23} of formula units

Thus 0.203 mole of CuSO_4 contains =\frac{6.023\times 10^{23}}{1}\times 0.203=1.23\times 10^{23} of formula units

The constant diameter of the double helix is ensured because hydrogen bonding is always between a(n)
vlada-n [284]

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.
