Calculating Amounts of Reactants and Products Solid lithium hydroxide is used in space vehicles to remove the carbon dioxide gas exhaled by astronauts. The hydroxide reacts with the carbon dioxide to form solid lithium carbonate and liquid water. How many grams of carbon dioxide can be absorbed by 1.00 g of lithium hydroxide? Methanol, CH3OH, reacts with oxygen from air in a combustion reaction to form water and carbon dioxide. What mass of water is produced in the combustion of 23.6 g of methanol?
Answer : Step 1 1 Balance the equation for the reaction. 2 Convert the known mass of the reactant or product to moles of that substance. 3 Use the balanced equation to set up the appropriate mole ratios. 4 Use the appropriate mole ratios to calculate the number of moles of the desired reactant or product. 5 Convert from moles back to grams if required by the problem The LiOH can absorb 919.9 g of carbon dioxide.
