To calculate the number of grams of carbon dioxide that can be absorbed by a complete reaction with a solution of sodium hydroxide, we need to determine the stoichiometry of the reaction.
The balanced equation for the reaction between sodium hydroxide (NaOH) and carbon dioxide (CO2) is:
2NaOH + CO2 -> Na2CO3 + H2O
From the balanced equation, we can see that for every 1 mole of CO2, we need 2 moles of NaOH.
Step 1: Convert the given mass of NaOH to moles.
To do this, we need the molar mass of NaOH, which is approximately 40.00 g/mol (sodium: 22.99 g/mol, oxygen: 16.00 g/mol, hydrogen: 1.01 g/mol).
Number of moles of NaOH = mass of NaOH / molar mass of NaOH
= 5.00 g / 40.00 g/mol
= 0.125 mol
Step 2: Determine the number of moles of CO2 using the stoichiometric ratio.
From the balanced equation, we know that for every 2 moles of NaOH, we need 1 mole of CO2.
Number of moles of CO2 = (0.125 mol NaOH) / (2 mol NaOH per 1 mol CO2)
= 0.125 mol / 2
= 0.0625 mol
Step 3: Convert the number of moles of CO2 to grams.
To do this, we need the molar mass of CO2, which is approximately 44.01 g/mol (carbon: 12.01 g/mol, oxygen: 16.00 g/mol).
Mass of CO2 = number of moles of CO2 * molar mass of CO2
= 0.0625 mol * 44.01 g/mol
= 2.75 g
Therefore, the number of grams of carbon dioxide that can be absorbed by a complete reaction with a solution containing 5.00 grams of sodium hydroxide is 2.75 grams.
