Answer:
2.77 moles
Step-by-step explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = (N)/(L) \\](https://img.qammunity.org/2023/formulas/chemistry/college/dy5cvg3ucsyez167b5w2yxtkokc1inq3ag.png)
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.67 x 1024 carbon atoms
We have
![n = \frac{1.67 * {10}^(24) }{6.02 * {10}^(23) } = 2.774086 \\](https://img.qammunity.org/2023/formulas/chemistry/college/owlnev55gs7p0hnfpodrtx2ielxdnkkcvf.png)
We have the final answer as
2.77 moles
