106.7g + 0.25g + 0.195g = 107.145
since 106.7 has the most uncertainty(+- 0.1) the answer round off to 1 decimal place
final answer is 107.1 g
35.45 mL - 30.5mL = 4.95mL
most uncertainty is +-0.1ml so the anwer off to one decimal.
5.0 mL is the final answer
when adding and subtracting the measurements the answer carries the same number of decimal as the quantity carrying the fewest decimal places
12.04 x 5.4 = 65.016
12.04 has 4 significant figure , 5.4 has 2 significant figure . 5.4 has the fewest signicant figure therefore the final answer is 65
answer carries the same number of significant numbers as the factor with the fewest significant figures.
