For the following problems, please show the answer with 1 more sig fig or 1 more decimal place with units (and if need to be Scientific notation) and then the answer in the correct number of sig fig with units (and if needed in Scientific notation).
1) 3.21m + 0.753m + 21.4m = __________________ = ____________________
2) ( 3.21E-4 m) ( 6.21E9m) = ____________________ = _____________________
3) 13.210 L - 0.753 L = __________________ = ____________________
4) 4.28E7g / 2.13E-3 sec = _________________ = _____________________
5. (8.03E-5sec) (3.72E-2sec) = ___________________ = _______________________

6. What is the density of a substance that has a volume of 32.7 mL and a mass of 124.1g ?
7. What is the density of the solid that has a mass of 23.5g and the volume was found the water displacement. The volume of the water before adding the solid was 15.32mL and after adding the solid, the resulting volume is 26.47mL.
8. If the actual density of the solid from Question 7 was 2.67g/mL and you can assume that the answer to Question 7 is the experimental value, determine the Error and Percent Error.
