adding & rounding off

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

subtraction & rounding off

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

adding and subracting

Multiplication and rounding off

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
