Question

how many times is one atom of carbon heavier than one atom of oxygen.

Answer 1

one carbon and and one oxygen is added for the successive member

Answer 2

Answer:

One atom of oxygen is heavier than one carbon atom

Explanation:

Oxygen is more heavier by 4u

we can find it by $\frac{mass of carbon }{mass of oxygen}$ = $\frac{12}{16}$ = $\frac{3}{4}$ times

so oxygen is more heavier than carbon ie mass of oxygen is greater by  $\frac{3}{4}$ times mass of carbon
