Question

How many carbon atoms are there in 1.00 mol of C2H6?

a) 4.82 x 10^24
b) 3.01 x 10^23
c) 6.02 x 10^23
d) None of the above

Answer 1

There are 1.2044 × 1024 carbon atoms in 1.00 mol of C2H6, so the correct answer is d) None of the above.

Step-by-step explanation:

To determine how many carbon atoms are there in 1.00 mol of C2H6, one should know that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.), which is 6.022 × 1023.

As each molecule of ethane (C2H6) contains 2 carbon atoms, we need to multiply Avogadro's number by 2 to find the total number of carbon atoms in 1.00 mole of ethane.

6.022 × 1023 molecules/mol × 2 carbon atoms/molecule = 1.2044 × 1024 carbon atoms.

Therefore, the correct answer is d) None of the above.
