How many times is one Argon atom heavier than one oxygen atom, if the Relative Atomic Mass of Argon is 40.[Relative atomic mass: O=16]

argon is 2.5 times heavier than oxygen

Explanation:

Given that;

Relative atomic mass of argon = 40

Relative atomic mass of hydrogen = 16

Ratio of the relative atomic mass of argon to that of oxygen = 40/16 = 2.5

Therefore, argon is 2.5 times heavier than oxygen.
