Unit 1C Significant Figures Practice Problems Name: Date: Work each of the following problems. SHOW ALL WORK. 1. Determine the number of significant figures in the following measurements: 13,465 m = 1,065 cm = 0.0045 g = 23,000 L = 0.0302 s = 160 kg = 1,030 mL = 1.500 g = 7,685 m = 3,054,000 L = 5 4 2 2 3 2 3 4 4 4 2. Solve the following operations and express the final answer with the correct number of significant figures: 2.052 mm + 1.54 mm = 3.592 mm, 4 sigfigs 11.29 g + 1.57 g + 2.0 g = 14.86 g, 4 sigfigs 7,052.1 L - 2,048.02 L = 500408 L, 6 sigfigs 32.467 s - 3.21 s = 29.257 s, 5 sigfigs questions continued on next page Unit 1C_Practice Problems STUDENT Copyright © 2018 Georgia Public Broadcasting.
