Solid lithium hydroxide is used in space vehicles to remove exhaled carbon dioxide. The products are solid lithium carbonate and liquid water. What mass of carbon dioxide gas can 1021 g of lithium hydroxide absorb? (Write the balanced chemical equation for the reaction first.) How many grams of water will be produced? (Thank you for your help, I'm trying to get the hang of Chemistry... it's really not my thing):)
