Identify the number of significant figures in each measurement:

- 2.20 lb
- 95 g Silver
- 28 miles

Choose from the following options for each measurement:

- One significant figure
- Two significant figures
- Three significant figures
- Four significant figures

A. Convert [tex]5.91 \times 10^{-5}[/tex] L to picoliters.
Express your answer with the appropriate units using metric symbols.

C. Convert [tex]7 \times 10^{-4}[/tex] kg to micrograms.
Express your answer with the appropriate units using metric symbols.

D. Convert [tex]7.8 \times 10^{10}[/tex] picoseconds to seconds.
Express your answer with the appropriate units using metric symbols.

The units 2.20LB, 95g Sliver, and 28 miles have three, two, and two significant figures respectively. Also, 5.91×10−5 L is 5.91×10^7 pL, 7×10−4 kg is 7×10^8 μg, and 7.8×10^10 ps is 78 seconds.

Explanation:

The number of significant figures in the given measurements can be figured out as follows:

2.20LB has three significant figures as zeroes appearing between other digits are significant.
95g Sliver has two significant figures.
28 miles has two significant figures.

For the conversions:

A: 5.91×10−5 L equals 5.91×107 picoliters (pL). The prefix 'pico' means 10^-12.
C: 7×10−4 kg equals 7×108 micrograms (μg). The prefix 'micro' indicates 10^-6.
D: 7.8×1010 picoseconds (ps) equals 78 seconds. The prefix 'pico' stands for 10^-12, so when converting it to seconds, the exponent of 10 will decrease by 12.
