Referring only to Table 1.2 , answer the following questions: a . Devices are available that allow liquid volumes as small as one microliter ( μL ) to be measured. How many microliters would be contained in 1.00 liter ? b . Electrical power is often measured in kilowatts. How many watts would equal 75 kilowatts ? c . Ultrasound is sound of such high frequency that it cannot be heard. The frequency is measured in hertz (vibrations per second). How many hertz correspond to 15 megahertz ? d . A chlorine atom has a diameter of 200 picometers . How many meters is this diameter?
