Lab 2.1
The Mass of Dissolved Salt
Experimental Errors:
ALL LEAD TO DECREASE IN MASS
1. Cap not on tight--> water spills out
2. Cleaning pan between Mi and Mf
3. Salt spills when pouring into bottle
4. Not shaken enough
5. Cap isn't fully dry
6. Remove cap before Mf
7. Outside of bottle is wet
-------------------------------------------------------------------------------------------------------
Make sure to:
1. Consider the sensitivity of balance. + or - 0.02
2. 15 out of 18 show a decrease in mass
3. Balances aren't all the same; errors
