Answer:
0.13 grams.
Step-by-step explanation:
To calculate the mass of iron(III) oxide that contains a trillion oxygen atoms, we first need to determine the molar mass of iron(III) oxide, also known as ferric oxide or Fe2O3. The molar mass of Fe2O3 is approximately 159.69 g/mol.
Next, we need to convert the number of oxygen atoms to moles using Avogadro's number, which is 6.022 x 10^23 atoms/mol. One mole of Fe2O3 contains two moles of oxygen, so the number of moles of Fe2O3 can be calculated as:
(1 trillion oxygen atoms) / (2 * 6.022 x 10^23 atoms/mol) = 8.37 x 10^-12 moles
Finally, we can calculate the mass of iron(III) oxide as:
(8.37 x 10^-12 moles) * (159.69 g/mol) = approximately 0.13 g
So, the mass of iron(III) oxide that contains a trillion oxygen atoms is approximately 0.13 grams.
