Answer:
1.33 × 10² 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/2021/formulas/chemistry/high-school/ak7k0w4ze80j1ablopkgu8j8wur48jz22k.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 we have
![n = \frac{8.02 * {10}^(25) }{6.02 * {10}^(23) } \\ \\ = 1.33 * {10}^(2) \: \: \: moles](https://img.qammunity.org/2021/formulas/chemistry/high-school/iw0ffah9rsbcpp1j0k67syiboxr0fuyu0i.png)
