Significant Figure Calculations ? Answers
Solve the following mathematical problems such that the answers have the correct number of significant figures:
1) 334.540 grams + 198.9916 grams = 533.532 g (rounded from 533.5316 g)
334.540 grams + 198.9916 grams
533.5316 g 533.532 g
Addition and subtraction rule- round to least significant number ? which is the one farthest to the left. (+ or - = Position Rule)
2) 34 grams / 10.1 mL = 3.4 g/mL (rounded from 3.366 g/mL) Multiplication or division rule is round to least # of digits. (X or / = least # of digits)
3) 2.61 x 106 joules / 0.0034 seconds = 7.7 X 10 8 J/s (rounded from 7.676 x 108 J/s)
4) 0.0610 m ? 0.18 m = -0.12 m (rounded from -0.119 m)
0.0610 m ? 0.18?? m ? 0.119 ? 0.12 m
Addition and subtraction rule- round to least significant number ? which is the one farthest to the left. (+ or - = Position Rule)
5) 349.0 cm + 1.10 cm + 100. cm = 450. cm (rounded from 450.1 cm)
349.0 cm 1.10 cm
+100. Cm 450.1 cm 450. cm or 4.50 X 10 2 cm
(Either uses decimal next to zero or scientific notation to show significant figures)
6) 252 meters / 910 seconds = 0.28 m/s (rounded from 0.2769 m/s)
7) 248.01010 kilograms + 84.097 kilograms = 332.107 kg (rounded from 332.1071 kg)
8) 44 m/s x 20 s = 900 m (rounded from 880 m) ( No decimal so best to assume 1 SF)
