When adding or dividing measured numbers, we don’t count significant figures. Instead, we look at the precision of the measured numbers. The answer can only be as precise as the least precise measurement.
Perform the calculations below and give the results with correct significant figures.
31.816 g + 4.23 g + 0.097 g =
3.48 m × 5.916 m × 19.27 m =
(0.0451 × 2.007 × 104) − (28.16 ÷ 0.874) =
g
m3
Question 1: Determine whether the answer to each calculation has the correct number of significant figures. If not,
correct it:
1A) 89.763 + 22.4581 = 3.997
1B) 4.32x1012 ÷ 3.1x104 = 1.4x1016
Question 2: Perform this calculation to the correct number of significant figures
9443 + 45 – 9.9 x 8.1x106
Question 3: Perform the following conversions:
3A) 78.3 cm to inches
3B) 22.5 lbs. to micrograms
3C) 396 in to L
4A) A new penny has a mass of 2.49g and a volume of 0.349cm³. Is the penny pure copper?
