1. If a small amount of hydrogen gas escaped unnoticed from the buret, would your calculated value of R be too low or high? Why?

2. if the volume of gas at the top of the inverted buret was not added to volume in the graduated region of the buret, would your calculated value of R be too low or too high? Why?

3. If the level of water in the buret was above the water level in the flask, and the height difference correction to the pressure was omitted, would your calculated value of R be too low or too high? Why
