Acruracy is how close a measurement is to the accepted value and is the clostest to the true value. Precision is how close measurements are to eachother and several measurements are repeatedly close. A significant didgit is a number that comes after a zero its really just any number besides zero. Based on my data the mass of 2 Liters of water is 2,000 g based on the knolage that one l Liter equals 1,000 mm.
What I learned about makeing measurements that i didnt know untill today was that you have to make sure that you are accactly presise with your measurements in science. Also you should make sure that what ever you are measuring that us measure it to the nearest 100th because then your measurement will be more persise.
well done. Keep this in mind all year.
