Ahmad Alexander · Answer 1

c. 0.30

Explanation:

One C atom has a mass of 12.0 u and one Ar atom has a mass of 40.0 u.

Let's assume that there are n atoms of C and n atoms of Ar. Then

Mass of n C atoms = n * 12.0

Mass of n C atoms = 12.0n u

Mass of n Ar atoms = n * 40.0

Mass of n Ar atoms = 40.0n u

ratio = mass of C/mass of Ar

ratio = 12.0n/40.0n

ratio = 0.300
