Question

How many moles of AgCl are there in 1.8 x 1024 molecules of AgCl?

(A) 30
(B) 0.33
(C) 3.0
(D) 300

Answer 1

The number of moles of AgCl in 1.8 x 10²⁴ molecules is 3.0 moles.

Step-by-step explanation:

To determine the number of moles of AgCl, we can use the Avogadro's number. Avogadro's number represents the number of particles (molecules or atoms) in one mole of a substance, which is approximately 6.022 x 10²³. Given that there are 1.8 x 10²⁴ molecules of AgCl, we can divide this number by Avogadro's number to find the number of moles:

Number of moles of AgCl = (1.8 x 10²⁴) / (6.022 x 10²³) = 3.0 moles

Therefore, the correct answer is (C) 3.0 moles.
