select the correct answer. rachel has a sample containing 2 moles of carbon. how many atoms of carbon are in this sample? a. 2.044×10²³ atoms b. 6.022×20²³ atoms c. 1.204×10²⁴ atoms d. 6.022×10⁴⁶ atoms

Answer

Explanation:

Step1: Recall Avogadro's number

1 mole of any substance contains $6.022\times 10^{23}$ atoms.

Step2: Calculate number of carbon atoms

For 2 moles of carbon, the number of atoms $n = 2\times(6.022\times 10^{23})$. $n=1.2044\times 10^{24}\approx1.204\times 10^{24}$ atoms.

Answer:

C. $1.204\times 10^{24}$ atoms
