Sodium metal reacts vigorously with water. A piece of sodium weighing 9.85 grams was added to a beaker containing 63.11 grams of water. During reaction, hydrogen gas was produced and bubbled from the solution. The final solution, containing sodium hydroxide, weighed 72.53 grams.
How many grams of hydrogen gas were produced?
If the density of hydrogen gas is 0.0813 g/L, what volume of hydrogen gas was produced?
