Convert 1.55 moles of KrF[tex]\(_2\)[/tex] to molecules.

Answer :

To convert moles of KrF₂ to molecules, we use Avogadro's number, which is a fundamental constant in chemistry. Avogadro's number tells us the number of molecules in one mole of any substance, and it is approximately [tex]\(6.022 \times 10^{23}\)[/tex] molecules per mole.

Here's how you can solve the problem step-by-step:

1. Identify the given amount in moles: You're provided with 1.55 moles of KrF₂.

2. Use Avogadro's number for conversion: Multiply the number of moles by Avogadro’s number to find the number of molecules.

- Formula:
[tex]\[
\text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number}
\][/tex]

- In mathematical terms:
[tex]\[
\text{Number of molecules} = 1.55 \text{ moles} \times 6.022 \times 10^{23} \text{ molecules/mole}
\][/tex]

3. Calculate the result: By performing the multiplication, you find the number of molecules:

[tex]\[
\approx 9.334 \times 10^{23} \text{ molecules}
\][/tex]

Thus, 1.55 moles of KrF₂ is approximately [tex]\(9.334 \times 10^{23}\)[/tex] molecules.
