How many fluorine atoms are there in 65 g of CF₄ A) 0.74 atoms B) 3.0 atoms C) 4.5 * 10²³ atoms D) 1.8 * 10²⁴ atoms E) 2.4 * 10²³ atoms

Question

Quizplus · Accepted Answer

The molar mass of CF4 is 88 g/mol. 65 g of CF4 is 65/88 moles. Each molecule of CF4 contains 4 fluorine atoms. Using Avogadro's number (6.022 * 10^23), the number of fluorine atoms is 4 * (65/88) * 6.022 * 10^23 = 1.8 * 10^24 atoms.
