Question

How many carbon atoms are present in 0.46 moles of C2H6O?

A. .92 carbon atoms
B. 2.77 x 10 23 carbon atoms
C. 5.5 x10 23 carbon atoms
D. You do not have enough information to calculate.

Answer 1

To find the number of carbon atoms in 0.46 moles of C2H6O, multiply the moles by 2 (since there are 2 carbons in each molecule), and then by Avogadro's number, yielding 5.54 × 10²³ carbon atoms, so the correct answer is C.

Step-by-step explanation:

To find the number of carbon atoms in 0.46 moles of C2H6O, we have to consider that each molecule of C2H6O contains 2 carbon atoms. We can use Avogadro's number, which is 6.022 × 10²³ atoms per mole, to calculate the total number of carbon atoms.

First, we multiply the number of moles of C2H6O by the number of carbon atoms in one mole of the compound:

0.46 moles C2H6O × 2 carbon atoms/mole C2H6O = 0.92 moles of carbon atoms.

Next, we multiply the moles of carbon by Avogadro's number:

0.92 moles of carbon atoms × 6.022 × 10²³ atoms/mole = 5.54 × 10²³ carbon atoms.

Therefore, the correct answer is C. 5.5 × 10²³ carbon atoms.

Answer 2

Here, Number of atoms = 0.46 * 6.23 * 10^23 [ Avogadro's number ]
= 2.77 * 10^23

In short, Your Answer would be Option B

Hope this helps!
