Answer :
There are [tex]6.022 \times 10^{23}[/tex] atoms of chlorine in 35.5 grams of chlorine.
Step 1: Determine the molar mass of chlorine.
Chlorine (Cl) has an average atomic mass of approximately 35.5 g/mol.
Step 2: Calculate the number of moles of chlorine in 35.5 grams.
Using the formula:
[tex]\text{number of moles} = \frac{\text{mass}}{\text{molar mass}}[/tex]
Substitute the given values:
[tex]\text{number of moles} = \frac{35.5 \text{ g}}{35.5 \text{ g/mol}} = 1 \text{ mole}[/tex]
Step 3: Use Avogadro's number to find the number of atoms.
Avogadro's number is approximately [tex]6.022 \times 10^{23}[/tex] atoms per mole.
Now, multiply the number of moles by Avogadro's number:
[tex]\text{number of atoms} = 1 \text{ mole} \times 6.022 \times 10^{23}\text{ atoms/mole} = 6.022 \times 10^{23} \text{ atoms}[/tex]
Final answer:
To calculate the total number of atoms of chlorine in 35.5g of chlorine atoms, use Avogadro's number and the molar mass of chlorine.
Explanation:
To calculate the total number of atoms of chlorine in 35.5g of chlorine atoms, we'll need to use Avogadro's number. The molar mass of chlorine is approximately 35.5g/mol. Since 1 mole of chlorine atoms contains 6.022 × 10^23 atoms, we can find the number of moles in 35.5g:
Number of moles = Mass / Molar mass = 35.5g / 35.5g/mol = 1 mole
Therefore, there are 6.022 × 10^23 atoms of chlorine in 35.5g of chlorine atoms.
