The chemical equation below shows the reaction between carbon dioxide (co2) and lithium hydroxide (lioh). co2 + 2lioh mc011-1.jpg li2co3 + h2o the molar mass co2 is 44.01 g/mol. how many moles of lioh are needed to react completely with 25.5 g of co2?

From the given balanced chemical equation,
                            CO2 + 2LiOH --> Li2CO3 + H2O
we can conclude that for every 2 moles of LiOH, we need a mole of CO2. Calculate first the number of moles of CO2 by dividing the given mass by the molar mass giving us an answer of 0.58 moles. Using proportionality,
                             0.58 / x = 1 / 2
The value of x is equal to 1.16 moles.
