Calculate the mass of sodium carbonate produced by passing 44.8 liters of carbon dioxide

Calculate the mass of sodium carbonate produced by passing 44.8 liters of carbon dioxide through an excess of sodium hydroxide solution.

1. We write down the equation of the reaction proceeding when passing carbon dioxide through an alkali solution:

2NaOH + CO2 = Na2CO3 + H2O;

2. calculate the chemical amount of gas:

n (CO2) = V (CO2): Vm = 44.8: 22.4 = 2 mol;

3. Determine the amount and calculate the mass of the formed sodium carbonate:

n (Na2CO3) = n (CO2) = 2 mol;

m (Na2CO3) = n (Na2CO3) * M (Na2CO3);

M (Na2CO3) = 2 * 23 + 12 + 3 * 16 = 106 g / mol;

m (Na2CO3) = 2 * 106 = 212 g.

Answer: 212
