If 24.6 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 301 Kelvin and 1.01 atmospheres? Show all of the work used to solve this problem. 

2 Li (s) + 2 H2O (l) 2 LiOH (aq) + H2 (g) can you help me step by step includ answer

aaronq · Answer

find moles of Li, then find the moles of H2 using a ratio and their coefficients, like this:$$\frac{ n _{Li} }{ 2 }=\frac{ n _{H2} }{ 1 }$$

once you find the moles of H2, use the ideal gas law, PV=nRT with the parameters given in the question.
