The volume of an irregularly shaped object is measured as 54.61 cm3. What is this volume in cubic meters? When reporting the measurement of volume after using a graduated cylinder, how many sig figs are you supposed to have? Which of the following volumes is equal to 30 mL...
Convert 3 ppm to mg/mL How many ppm is a concentration of 1 mg in 1 kg? Convert 25 weight/volume % to ppm. Express 46 ppm as a W/W concentration. If a soil holds 16 meq of Mg^{2+} per 100 g, how many ppm (parts per million) would this equal?

Plasma levels of GDF11 were below detection (0.43 ng ml À 1) in serum from mice and monkeys (Fig. 5d). These data suggest more equal contributions of GDF8 and activin A to regulation of lean body mass in monkeys and humans than mice and with little contribution from GDF11. This is...

You have two masses of equal volume: Mass A is denser than Mass B. You place them both into a container of water. Consider the following possible outcomes and determine which mass (if either has a larger bouyant force. Please E...
Why is -8^2 equal to -64? Why are these two equal? \tan^2(t) + \sin^2(t) = \sec^2(t) - \cos^2(t) Why is 0^{\infy} not indeterminate? Why is 1/x divergent? Why is 2 - (-2) actually +4? If f(x) = 4x - 3, what is f^{-1}(x)?
Calculate the molar mass of a gas if 0.125 g of the gas occupies 93.3 mL at STP. An ideal gas occupies a volume of 2.0 cm3 at 20 degrees Celsius and atmospheric pressure. Determine the number of molecules of gas in the container. A gas occupies a volume of 140 ml at 35.0 ...
Subsequently, undamaged or herbivore-damaged plants were enclosed in a frosted glass bottle (3142 cm3); a port at the bottom was used for the inlet of air, and a port at the top was used for the outlet of air. Plants in these bottles were used for the olfactometer bioassays and ...
A diver at a depth of 100 ft (pressure approximately 3 atm) exhales a small bubble of air with a volume equal to 100 mL. What will be the volume of the bubble (assume the same amount of air) at the surface? The density of air at 20 degrees C and 1.00 atm is 1.025g/L. If ...
