Answer to Question #22594 in Organic Chemistry for Amanda Moultrie
I need to know how to do the equation as well. I was never taught how to do this.
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(CO2) = 1/2 n (NaOH)
n(CO2) = 0.125/2 = 0.0625 mol
m(CO2) = M*n
M(CO2) = 12 + 16*2 = 44 g/mol
m(CO2) = 44 g/mol * 0.0625 mol = 2.75 g
Answer: 2.75 g
