How many iron atoms are in 0.32 mol of Fe2031? 3.9x 1023 jron atoms O 3.9 iron atoms O 6.02 x 1023 iron atoms 1.9 x 1023 iron at
Gennadij [26K]

Answer: 3.9\times 10^{23} iron atoms

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

1 molecule of [tex]Fe_2O_3 contains= 2 atoms of iron

1 mole of [tex]Fe_2O_3 contains=2\times 6.023\times 10^{23}=12.05\times 10^{23}  atoms of iron

thus 0.32 moles of Fe_2O_3 contains=\frac{12.05\times 10^{23}}{1}\times 0.32=3.9\times 10^{23}  atoms  of iron

Thus the sample would have 3.9\times 10^{23} iron atoms.
