A researcher places 2 grams of lithium into a large beaker


A researcher places 2 grams of lithium into a large beaker of water and catches the hydrogen gas being evolved. Since the water had a small drop of phenolphthalein indicator, the indicator turned a red color indicating that a base, lithium hydroxide was formed. How many Liters of hydrogen gas were evolved? The density of hydrogen gas is: 0.089 g/L Remember, hydrogen gas is diatomic.

1. 9.572 Liters of Hydrogen gas evolved

2. 0.0045 Liters of Hydrogen gas evolved

3. 18.54 Liters of Hydrogen gas evolved

4. 3.237 Liters of Hydrogen gas evolved

5. 0.783 Liters of Hydrogen gas evolved
