# Calculate the mass of sodium carbonate produced by passing 44.8 L of carbon dioxide through an excess

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

When carbon dioxide is passed through an excess of sodium hydroxide solution, sodium carbonate is synthesized. The reaction is described by the following equation:

2NaOH + CO2 = Na2CO3 + H2O;

When 1 mol of gas is dissolved, 1 mol of soda is synthesized. Let’s calculate the amount of carbon dioxide available. To do this, we divide the volume of gas by the volume of 1 mole of gas. 1 mole of ideal gas fills a volume of 22.4 liters under normal conditions.

N CO2 = 44.8 / 22.4 = 2 mol;

Let’s calculate the weight of this amount of soda. To do this, we multiply the amount of the substance by its molar weight.

M Na2CO3 = 23 x 2 + 12 + 16 x 3 = 106 grams / mol;

m Na2CO3 = 2 x 106 = 212 grams;
