How many atoms are in 1.5 moles of iron?
Answer:
One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.
The number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms
From the question,
We are to determine the number of atoms present in 1.5 moles of iron.
From the formula,
[tex]Number\ of\ moles = \frac{Number\ of\ atoms}{Avogadro's\ constant}[/tex]
Then, we can write that
Number of atoms = Number of moles × Avogadro's constant
∴ Number of atoms of iron present = 1.5 × 6.022×10²³
Number of atoms of iron present = 9.033 ×10²³ atoms
Number of atoms of iron present ≅ 9.0 ×10²³ atoms
Hence, the number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms
