what mass in grams of sodium hydroxide is produced if 20.0g of sodium metal reacts with excess water according ro the chemical equation, Na(s)+H2O4->naoh(aq)+h2(g)
mols Na metal = grams/molar mass = ?
Convert mols Na to mols NaOH using the coefficients in the balanced equation.
Then convert mols NaOH to g. g = mols x molar mass.
