Question

How many picograms are in 5.59 × 10–11 grams?

How many micrometers are in 6.36 × 10–5 meters?

How many kilovolts are in 3.48 × 105 volts?

How many nanoliters are in 1.58 × 10–10 liters?

Question 2

While driving your rental car on your trip to Europe, you find that you are getting 8.1 kilometers per liter of gasoline. What does this correspond to in miles per gallon?

Answer 1

a) According to the definition of picogram,1 picogram = 10^-12 gram.

Therefore, 5.59*10^-11g = 55.9*10^-12g

= 55.9 picogram

b) According to the definition of micrometer, 1 micrometer = 10^-6meter.

Therefore, 6.36*10^-5 meters = 63.6*10^-6 meters.

= 63.6 micrometer.

c) According to the definition of  kilovolt, 1 kilovolt = 10³ volt.

Therefore, 3.48 × 10⁵ volts = 0.0348*10³ volts.

= 0.0348 kilovolts.

d) According to the definition of  nanoliter, 1 nanoliter = 10^-9 liter.

Therefore, 1.58 × 10^–10 liters = 0.158*10^-9 liter.

= 0.158 nanoliter.

Question:-2 The conversion factor for kilometers per liter to miles per gallon is shown below.

1 kilometer per liter = 2.35215 miles per gallon.

Therefore, 8.1*2.35215 = 19.052415 miles per gallon
