Question

what is the ratio between masses of carbon and oxygen in co2(c=12u,o=16u)

Answer 1

HEY DEAR,

HERE IS YOUR ANSWER.......

IN CASE OF CO2

MASS OF CARBON = 12u.

MASS OF OXYGEN = 32u.

so,

RATIO OF MASS OF CARBON AND OXYGEN

      C:O => 12:32

               =>3:8

HOPE IT HELPS YOU....

Answer 2

Answer:

The ratio of the masses of carbon to the  oxygen in CO₂ is $3:8$.

Explanation:

Data given,

The atomic mass of carbon = $12u$

The atomic mass of oxygen = $16u$

The ratio of the masses of carbon to the oxygen in CO₂ =?

As we know,

• In 1 mole of CO₂, one carbon atom and two oxygen atoms are present.

Therefore,

• The atomic mass of 1 carbon atom = 1 × atomic mass of carbon.
• The atomic mass of 1 carbon atom = $1 \times 12$ = $12u$

Now,

• The atomic mass of 2 oxygen atoms = 2 × atomic mass of oxygen.
• The atomic mass of 2 oxygen atoms = $2\times 16$ = $32u$

Therefore,

• The ratio between the masses of carbon and oxygen in CO₂ is: $\frac{mass of 1 C-atom}{mass of 2O-atoms}$ = $\frac{12u}{32u}$ =$\frac{3}{8}$.

Hence,

• Ratio = $3:8$.
