1. Accuracy is how close the measurements are to the correct value. Precision is how close each measurements are to each other.
2. An electronic balance is precise and accurate, but a triple beam balance is precise and not accurate.
3. A significant digit is all non-zero digits.
4. According to my data, there would be 1,999.273 grams in 2 Liters.
Summary:
I did not know how to find a volume of an object. I learned that to do that, you need to fill a graduated cylinder with water and put the object in. However many milliliters the water rose is the volume. I also learned about a significant digit and the difference between precise and accuracy. I learned that it is very important to be as precise as possible.
Nice Job. Thanks for posting.
