Which has the greatest number of molecules?

Question

Quizplus · Accepted Answer

We need to calculate the number of molecules for each option using the formula:
Number of molecules = (mass in grams/molecular weight) x Avogadro's number (6.022 x 10^23)
A) Number of molecules of nitrogen = (28/28) x 6.022 x 10^23 = 6.022 x 10^23
B) Number of molecules of oxygen = (32/32) x 6.022 x 10^23 = 6.022 x 10^23
C) Number of molecules of methane = (32/16) x 6.022 x 10^23 = 1.2044 x 10^24
D) Number of molecules of fluorine = (38/38) x 6.022 x 10^23 = 6.022 x 10^23

Out of the four options, option C has the greatest number of molecules with 1.2044 x 10^24 molecules.
