# Answer to Question #22594 in Organic Chemistry for Amanda Moultrie

Question #22594

Balanced equation 2NaOH (aq) + CO2 --> Na2CO3 (aq) + H2O Calculate the number of grams of carbon dioxide that can be absorbed by complete reaction with a solution that contains 5.00 g of sodium hydroxide.

I need to know how to do the equation as well. I was never taught how to do this.

Expert's answer

2NaOH + CO

First calculate the amount of substance of sodiumhydroxide:

n(NaOH) = m/M

n(NaOH) = 5/M

M(NaOH) = 23 + 16 + 1 = 40 g/mol

n(NaOH) = 5 g / 40 g/mol = 0.125 g/mol

n(CO

n(CO

m(CO

M(CO

m(CO

Answer: 2.75 g

_{2}= Na_{2}CO_{3}+ H_{2}OFirst calculate the amount of substance of sodiumhydroxide:

n(NaOH) = m/M

n(NaOH) = 5/M

M(NaOH) = 23 + 16 + 1 = 40 g/mol

n(NaOH) = 5 g / 40 g/mol = 0.125 g/mol

n(CO

_{2}) = 1/2 n (NaOH)n(CO

_{2}) = 0.125/2 = 0.0625 molm(CO

_{2}) = M*nM(CO

_{2}) = 12 + 16*2 = 44 g/molm(CO

_{2}) = 44 g/mol * 0.0625 mol = 2.75 gAnswer: 2.75 g
