Dissolving calcium hydroxide (∆Hsoln = -16.2 KJ/mol) in water is an exothermic process. How much lithium hydroxide (∆Hsoln = -23.6 KJ/mol) is needed to deliver the same amount of heat as 15.00 g of Ca(OH)2? Hello everyone, thank you for taking a look at m...

Thank you Dr. Bob. This is my work: 15g / 74.093 g Ca(OH)2 = 0.202 16.2 kJ/mol * 0.202 = 3.272 kJ 23.6 kJ/mol * X mol LiOH = 3.272 KJ X mol LiOH = 0.138 0.138 * 23.95 = 3.32 g LiOH
