Answer 3

Calculation of the Number of Atoms in 32g of Sulfur and 56g of Iron (Fe)

To determine which substance, sulfur (S) or iron (Fe), contains more atoms in a given mass, we need to calculate the number of moles for each element and then convert it to the number of atoms.

The molar mass of sulfur (S) is approximately 32.06 g/mol Therefore, in 32g of sulfur, we have:

Number of moles of sulfur = mass of sulfur / molar mass of sulfur Number of moles of sulfur = 32g / 32.06 g/mol ≈ 0.998 moles of sulfur

Avogadro's number states that 1 mole of any substance contains 6.022 x 10^23 atoms. Therefore, in 0.998 moles of sulfur, we have:

Number of atoms of sulfur = number of moles of sulfur x Avogadro's number Number of atoms of sulfur = 0.998 moles x 6.022 x 10^23 atoms/mol ≈ 6.01 x 10^23 atoms of sulfur

The molar mass of iron (Fe) is approximately 55.85 g/mol Therefore, in 56g of iron, we have:

Number of moles of iron = mass of iron / molar mass of iron Number of moles of iron = 56g / 55.85 g/mol ≈ 1.002 moles of iron

In 1.002 moles of iron, we have:

Number of atoms of iron = number of moles of iron x Avogadro's number Number of atoms of iron = 1.002 moles x 6.022 x 10^23 atoms/mol ≈ 6.04 x 10^23 atoms of iron

Conclusion

In 32g of sulfur, there are approximately 6.01 x 10^23 atoms of sulfur, while in 56g of iron, there are approximately 6.04 x 10^23 atoms of iron. Therefore, there are slightly more atoms in 56g of iron (Fe) compared to 32g of sulfur.

Please note that the calculations provided are approximate due to the rounded molar masses used.
