Sodium peroxide is used for air regeneration in submarines. The process takes place according to the scheme Na2O2 + CO2 -Na2CO3 + O2. How much carbon dioxide can be reduced with sodium peroxide weighing 7.8 kg?

1. Let us write the equation for the reaction of interaction of sodium peroxide with carbon dioxide with spaced coefficients:

2Na2O2 + 2CO2 = 2Na2CO3 + O2;

2. Find the molecular weight of sodium peroxide:

23 * 2 + 16 * 2 = 78 g / mol;

3. Find the amount of substance in sodium peroxide:

7800/78 = 100 mol;

4. The amount of substance in carbon dioxide is 100 mol, since the coefficients before sodium peroxide and carbon dioxide are equal. Let’s find the volume of carbon dioxide:

22.4 * 100 = 2240 liters;

Answer: The volume of carbon dioxide is 2240 liters.
