How many moles of sodium carbonate contain 1.773 × 10¹⁷carbon atoms? A) 2.945 × 10^-⁷ B) 8.836 × 10^-⁷ C) 5.890 × 10^-⁷ D) 9.817 × 10^-⁸ E) 1.473 × 10^-⁷

Question

Quizplus · Accepted Answer

Sodium carbonate (Na2CO3) has one carbon atom per molecule. Using Avogadro's number (6.022 × 10^23 atoms/mol), the number of moles is calculated as (1.773 × 10^17 atoms) / (6.022 × 10^23 atoms/mol) = 2.945 × 10^-7 moles.
