Answer 2

Given: 1 mole of oxygen atom

           1 mole of hydrogen atom

To find: How many times is 1 mole of oxygen atom heavier than 1 mole of hydrogen atom

Step by step Explanation:

Mass of 1 mole of oxygen atom: 16 g

Mass of 1 mole of hydrogen atom: 1.008 g

$=\frac{mass_{oxygen} }{mass_{hydrogen} } \\=\frac{16}{1.008} \\=15.87$

Therefore, it can be said that 1 mole of oxygen atom is nearly 16 times heavier than 1 mole of hydrogen atom.

Atomic mass of any atom is the measure of how heavy that atom is in comparison to mass of 1/12th of mass of carbon atom (carbon-12).

1 mole of any atom contains $6.02\times 10^{23}$ atoms.
