The 4 KO₂ (s) + 2 CO₂(g) → 2 K₂CO₃(s) + 3 O₂(g) What is the mass in grams of oxygen gas that can be produced from 0.327 grams of carbon dioxide?

Answer 1

Since we have a balanced reaction, we can use stoichiometry to find the answer.

First, we need to find the molar masses of CO₂ and O₂. The molar mass of CO₂ is 44 g/mol and 32 g/mol for O₂.

We change grams of CO₂ to moles. Then, we multiply by the stoichiometric ratio. Then we multiply by the molar mass of O₂ to get our answer in grams.

0.327 g CO₂ × (1mol CO₂/44 g CO₂ )× (3 mol O₂/2 mol CO₂ )×( 32 g/mol O₂ )= 0.357 g O₂
