mols Na = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols Na to mols H2.
Then mols H2 x (22.4 L/mol) = ?L H2 gas @ STP.
How much H2 gas at STP can be produced by
the reaction
2 Na(s) + 2 H2O(ℓ)heat−→ H2(g) + 2 NaOH(aq)
of 3.90 g of Na and excess water?
Answer in units of L.
