Use PV = nRT and solve for n. Remember that T must be in kelvin.
Then n = grams/molar mass. Solve for grams.
can someone solve this?(21.3 g Li/6.941 g Li/moleLi)*(1mole H2/1moleLi) * 22.4 L at STP * ( temp correction 297/273)* (pressure correction 1/1.4) = your answer in L of H2
maybe this is better
If 21.3 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 297 Kelvin and 1.40 atmospheres? Show all of the work used to solve this problem.
