22. Refer to Section 1.2. (a) 4020.6 mL 〓 4.0206 x 103 mL (b) 1.006 g (This is already in proper scientific notation.) (c) 100.1°C 〓 1.001 x 102°C 32. Refer to Section 1.2 and Table 1.2. Convert one of the numbers to the units of the other. Once the numbers are expressed in common units, they can be compared directly. (a) 37.12 g x

1k g 〓 0.03712 k g , thus: 37.12 g [ 0.3712 kg. 1000 g

(b) 28 m 3 × ?

? 100 cm ? 6 3 ? 〓 28 ×10 cm , thus: 28 m3 ] 28 x 102 cm3. ? 1m ?

(c) 525 mm ×

1m 1 nm × 〓 525 × 106 nm , ?9 1000 mm 1 × 10 m

thus 525 mm 〓 525 x 106 nm 48. Refer to Section 1.3. Calculate the volume of the object from the change in the volume of the graduated cylinder, then calculate the density.
