Solutions of sodium hydroxide cannot be kept for very long because they absorb carbon dioxide from the air , forming sodium carbonate. the unbalanced equation is

NaOH(aq) + CO2(g) = Na2CO3(aq) + H2O(l)

calculate the number of grams of carbon dioxide that can be absorbed by complete reation with a solution of 5.00 grams of sodium hydroxide

1. Balance the equation.
2. Convert 5.00 g NaOH to moles. moles = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles NaOH to moles CO2.
4. Convert moles CO2 to grams CO2.
grams = moles x molar mass.
Post your work if you get stuck.
