Question

How many mol of lithium are there in 1.204 x 1024 lithium atoms

Answer 1

Answer:

The answer is

2.0 moles

Explanation:

To find the number of moles of an element given the number of entities contained in that element , we use the formula

$n = \frac{N}{L}$

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 = 1.204 × 10²⁴ lithium atoms

We have

$n = \frac{1.204 \times {10}^{24} }{6.02 \times {10}^{23} }$

We have the final answer as

2 moles
