Carry out these operations as if they were calculations of experimental results, and express each answer in the correct units and with the correct number of significant figures: Part 1 of 4 (a) 7.1953 m + 0.2 m + 2.15 m = $oxed{}$ m Part 2 of 4 (b) 3.69 g - 2.0547 g = $oxed{}$ g Part 3 of 4 (c) 4.89 cm $\times$ 3.9355 cm = $oxed{}$ cm$^2$ Part 4 of 4 (d) $\frac{(2 \times 10^3 g + 7.471 g)}{(0.055 cm^3 - 0.013 cm^3)} = \boxed{} \frac{g}{cm^3}$

C. Determine the number of significant digits in each of the following: 1. 0.12090 mm 2. 0.0607 g 3. 250 4. 43.00 cm 5. 26.509 cm 6. 0.0200 g D. Round each of the following to the specified number of significant figures: 1. 1.7174 (to 4 significant figures) 2. 800.2 (to 4 significant figures) 3. 0.0006350 (to 3 significant figures) 4. 4.10 (to 3 significant figures) 5. 0.2670 (to 3 significant figures) E. Carry out the following operations to the proper number of significant figures: 1. 1.22145 + 56.1 = 2. 89.001 / 4000 = 3. 72.35 * 356 = 4. (87.1 - 23,456) * (78.44 + 21.33)
