Question

carbon dioxide, is 15 grams of carbon is taken, how many grams of oxygen is required?​

Answer 1

40 grams of O₂ will be required to react with 15 grams of carbon.

Explanation:

C + O₂ = CO₂;

1 mole of C reacts with 1 mole of O₂.

So,

12 grams of C reacts with 32 grams of O₂,

1 gram of C will react with $\frac{32}{12}$ grams of O₂.

15 grams of C will react with $15 * \frac{32}{12}$ grams of O₂.

Upon solving we get,

40 grams of O₂.
