What is the mass in grams of 9.76 × 10¹²atoms of naturally occurring sodium? A) 1.62 × 10^-¹¹ B) 7.05 × 10^-¹³ C) 2.24 × 10¹⁴ D) 22.99 E) 3.73 × 10^-¹⁰

Question

Quizplus · Accepted Answer

The molar mass of sodium is approximately 22.99 g/mol. Using Avogadro's number (6.022 × 10^23 atoms/mol), the mass of 9.76 × 10^12 atoms of sodium can be calculated as follows: (9.76 × 10^12 atoms) / (6.022 × 10^23 atoms/mol) × 22.99 g/mol = 3.73 × 10^-10 g.
