Two moles of LiOH removes one mole of CO2. 36 g of LiOH is 1.50 moles of LiOH. That will absorb 0.75 moles of CO2. Convert that to grams of CO2.

well, the moles will be proportional to pressure. Balance the equations: CH4+2O2>>CO2 + 2H20 **1 C2H6+7.5 O2>> 2CO2 + 3H2O **2 so in methane, one gets the same amount of CO2 as CH4 In the ethane, one gets twice as much. So,of the final pressure, the difference is ...

The equation tells you that 1 mole CaCO3 = 1 mole CaO = 1 mole CO2; therefore, 3 moles CaCO3 will produce 3 moles of both CaO and CO2. OR you can use the dimensional approach this way, 3 moles CaCO3 x (1 mole CO2/1 mole CaCO3) = 3 moles CO2. The numbers in the factor within ...

I don't know what all of the numbers mean since spacing is a problem here but I think what you want to do is to plot moles Na2CO3 used vs moles CO2 produced and see if you obtain a linear plot. If the mL you show is mL CO2, I would assume that also includes H2O so I would ...
