Explanation:

Step1: Recall metric - unit symbols

Measurement	Symbol
milligram	mg
liter	L
kilogram	kg
millimeter	mm
centimeter	cm
meter	m
millisecond	ms
kilometer	km
gram	g
microgram	μg
nanometer	nm

Step2: Correct the wrong - filled units in the questions

1. Colas may be purchased in two or three L bottles. (Correct)
2. The mass of bowling ball is 7.25 kg. (The original 'g' is too small for a bowling - ball mass)
3. The length of the common housefly is about 1 cm. (The original 'g' is a mass unit, should be a length unit)
4. The mass of a paper clip is about 1 g. (Correct)
5. One teaspoon of cough syrup has a volume of 5 mL. (Correct)
6. The speed limit on the highway is usually 106.6 km/h or 29 m/s. (MP is not a standard speed unit, should be km/h for kilometers per hour and m/s for meters per second)
7. The length of the small intestine in man is about 6.25 m. (The original 'L' is a volume unit, should be a length unit)
8. Viruses such as AIDS, polio and flu range in length from 17 to 1000 nm. (The original 'M' is not a proper unit for virus length, should be nm for nanometers)
9. Adults require 1,000 mg of calcium to meet the U.S. RDA. (The original 'g' is too large for daily calcium requirement)
10. In a vacuum, light can travel 300 km in 1 s. (Correct)
11. The mass of a proton is 1.67×10⁻²⁷ kg. (The original 'μg' is too large for a proton mass, the correct value is 1.67×10⁻²⁷ kg)
12. Blue light has a wavelength of about 500 nm. (The original 'M' is wrong, should be nm for nanometers)
13. One mole of oxygen gas at STP occupies 22.4 L. (The original 'g' is a mass unit, should be L for volume)
14. Myoglobin, a protein that stores oxygen, has a mass of 2.98×10⁻¹⁴ g. (Correct)
15. Buttery popcorn contained in a large 1 L bowl has a mass of about 50 g of fat. (Correct)
16. The dying comet fragments that continued to batter Jupiter travel at speeds of about 58,117 km/h or 130,000 miles per hour. (Fill in km/h for speed)
17. The human heart has a mass of about 1.05 kg. (A reasonable mass unit for a human heart)
18. Stand with your arms raised out to your side. The distance from your nose to your outstretched middle finger is about 1 m. (The original 'y' is not a standard unit, should be m)
19. The body mass of a flea is about 0.5 mg and it can jump about 20 cm high. (The original 'M' and 'My' are wrong, should be mg for mass and cm for height)
20. On a statistical basis, smoking a single cigarette lowers your life expectancy by 642,000 ms or 10.7 minutes. (The original 'μg' is a mass unit, should be ms for milliseconds)
