Answer to Question #111192 in General Chemistry for Devin Leung

Question

2LiOH(s) + CO2(g) --> Li2CO3(s) + H2O(l)
There is 3.0 L of CO2 gas at a pressure of 1.5 atm and a temperature of 300 K. What mass of LiOH would be used to react with this amount of CO2?

Answer 1

pV= nRT.

n= pV/RT = 1.5 x 3 / 0.082 x 300 = 0.182926829 moles of CO2

m= 2 x 0.182926829 x 24 = 8.7804878 g of LiOH
