Best ResponseYou've already chosen the best response.1omgz a medal so write an equation, balance it convert 240 mL of CO2 gas to moles (ps. 1 mole= 22.414 L) use the coefficients to find how many moles of Na2CO3 you need in this manner: if, aA + bB <> cC ..... moles of A/a=moles of C/c then convert to mass of Na2CO3 moles=mass/molar mass ps. disregard the density of acetic acid, it's just there to throw you off
