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?

An 11 lb bowling ball has a circumference of 27 inches. Calculate the density of the bowling ball and determine whether it will float or sink if placed in water. Ignore the holes in the bowling ball.
The density of mercury is 13.6 g/mL. Comment on how the density of mercury could cause environmental problems. Does mercury pose any other threat?
An under-inflated volleyball is pumped full of air so that its radius increases by 10%. Ignoring the mass of the air inserted into the ball, what will happen to the volleyball's density?
a. The density of the volleyball will increase by approximately 25%.
b. The density of the volleyball will increase by approximately 10%.
c. The density of the volleyball will decrease by approximately 10%.
d. The density of the volleyball will decrease by approximately 17%.
e. The density of the volleyball will decrease by approximately 25%
