Question

How many moles are in 3.94 x 1023 molecules of C6H14?

A. 0.654 moles
B. 4.57 x 1021 moles
C. 3.395 x 1025 moles
D. 2.37 x 10 47 moles

Answer 1

In 6.23 * 10^23 atoms, number of moles = 1
So, It would be: 3.94 * 10^23 / 6.23 * 10^23
= 0.654 moles

In short, Your Answer would be Option A

Hope this helps!
