Question

The chemical equation below shows the reaction between carbon dioxide (co2) and lithium hydroxide (lioh). Co2 + 2lioh right arrow. 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? 0. 290 0. 579 1. 16 1. 73.

Answer 1

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.
