Question

How many moles are in 3.2x10^23 molecules of C2H6O?

Options:
A. 0.1 moles
B. 0.2 moles
C. 0.5 moles
D. 0.01 moles

Answer 1

To find the number of moles in 3.2x10^23 molecules of C2H6O, divide the number of molecules by Avogadro's number, resulting in approximately 0.5 moles.

Step-by-step explanation:

To determine the number of moles in 3.2x1023 molecules of C2H6O, we need to use Avogadro's number, which is 6.022x1023 molecules per mole. By setting up a ratio, we have:

(3.2x1023 molecules C2H6O) / (6.022x1023 molecules/mol) = 0.531 moles C2H6O

However, since 0.531 is not an option provided, we should check the calculation for any mistakes. The correct method of division would actually give us:

(3.2x1023 molecules C2H6O) / (6.022x1023 molecules/mol) = approximately 0.53, which rounds to 0.5 moles of C2H6O.

Therefore, the answer to the question is C. 0.5 moles.
