How many moles are in [tex]$2.41 \times 10^{24}$[/tex] molecules of HCN?

[ ? ] mol HCN

Remember: 1 mole [tex]$= 6.02 \times 10^{23}$[/tex] particles.



Answer :

Of course! Let's find out how many moles are in [tex]\(2.41 \times 10^{24}\)[/tex] molecules of HCN step by step.

We know that Avogadro's number represents the number of particles in one mole. Avogadro's number is approximately [tex]\(6.02 \times 10^{23}\)[/tex] particles per mole.

Given:
- Number of molecules of HCN = [tex]\(2.41 \times 10^{24}\)[/tex]
- Avogadro's number = [tex]\(6.02 \times 10^{23}\)[/tex] particles/mole

The relationship between the number of particles and the number of moles is given by the formula:

[tex]\[ \text{Number of moles} = \frac{\text{Number of particles}}{\text{Avogadro's number}} \][/tex]

Substituting the given values into the formula:

[tex]\[ \text{Number of moles of HCN} = \frac{2.41 \times 10^{24} \text{ molecules}}{6.02 \times 10^{23} \text{ molecules/mole}} \][/tex]

When you carry out the division:

[tex]\[ \text{Number of moles of HCN} \approx 4.00 \text{ moles of HCN} \][/tex]

Therefore, there are approximately [tex]\(4.00\)[/tex] moles of HCN in [tex]\(2.41 \times 10^{24}\)[/tex] molecules of HCN.
