Question

How many moles of C3H8 contain 9.25 * 10²⁴ molecules of C3H8?

-65.1 moles C₃H₈
-34.9 moles C₃H₈
-28.6 moles C₃H₈
-46.2 moles C₃H₈
-15.4 moles C₃H₈

Answer 1

To find the number of moles of C3H8 containing a given number of molecules, divide the number of molecules by Avogadro's number.

Step-by-step explanation:

To determine the number of moles of C3H8 that contain 9.25 x 10^24 molecules of C3H8, we can use Avogadro's number. Avogadro's number is approximately 6.022 x 10^23 molecules per mole. So, to find the number of moles, divide the given number of molecules by Avogadro's number:

Moles of C3H8 = (9.25 x 10^24 molecules) / (6.022 x 10^23 molecules/mole) = 15.36 moles C3H8

Therefore, the correct answer is 15.4 moles C3H8.
