4.What is the number of significant figures in each of the following measurements? (8 points) 5.Express the results in the proper number of significant figures. (12 points) a. 5.6792 m + 0.6 m + 4.33 m=10.6092= 10.6m b. 3.70 g – 2.9133 g=0.7867= 0.79g c. 4.51 cm × 3.6666 cm= 16.536366= 16.54 cm 2 d. (3 × 10 4 g + 6.827g)/(0.043 cm 3 – 0.021 cm 3 )= 318.827/.022=14,492.136m 3 (Reference: Chang 1.35) 6.
