Investigating The Law Of Conservation Of Mass-Energy

Standard Equation:

Addition of two mass numbers along with uncertainty.

Question: Addition of mass of Compound A ± 0.01g + Compound B ± 0.01g = ?

Join now!

Mass of compound A (BaCl2) = 5.54 ± 0.01g

Mass of compound B (CuSo4)) = 10.86 ± 0.01g

  1. Add both of the masses together or insert in this formula: Compound A ± 0.01g + Compound B ± 0.01g = ?

            Mass of compound A (BaCl2) = 5.54 ± 0.01g

            Mass of compound B (CuSo4)) = 10.86 ± 0.01g

            5.54 ± 0.01g + 10.86 ± 0.01g = 16.4 g.

  1. To find the uncertainty in any type of addition or subtraction, you ...
