Question

How many moles of C8H18 contain 9.25 x 10²⁴ molecules of C₈H₁₈?

Answer 1

To find the number of moles of C8H18 that contain 9.25 x 10²´ molecules, we divide the number of molecules by Avogadro's number, resulting in 1.536 moles of C8H18.

Step-by-step explanation:

The student's question asks how many moles of C8H18 contain 9.25 x 10²´ molecules of C₈H₁₈. To answer this, we need to use Avogadro's number, which is 6.022 x 10²³ molecules per mole, a fundamental concept in chemistry.

First, we calculate the number of moles by dividing the number of molecules by Avogadro's number:

Number of moles = (9.25 x 10²´ molecules) / (6.022 x 10²³ molecules/mol)

Upon doing this calculation, we get:

Number of moles = 1.536 moles (approximately)

Therefore, 1.536 moles of C8H18 contains 9.25 x 10²´ molecules of C₈H₁₈.
