Question

Convert 4.36 x 1025 molecules of CH,OH to moles.

Answer 1

The answer is 72.43 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) \\`

From the question

N = 4.36 × 10^25 molecules

We have

`n = \frac{4.36 * {10}^(25) }{6.02 * {10}^(23) } \\ = 72.425249...`

We have the final answer as

72.43 moles
