Metallic sodium reacts violently with water to form hydrogen gas and sodium hydroxide according to the balanced equation:
2 Na(s) + 2H2O(1) – 2 NaOH(aq) + H2(g)
What is the volume of hydrogen gas produced when 2.500 grams of sodium react
with excess water at 2.10 atm pressure and 23.5°C temperature? (Three sig figs)
Give your answer with three 3 significant figures
Hint: You must first solve for the moles of H2
