International computer communications are often carried by optical fibers incables laid along the ocean floor. If one strand of optical fiber weighs 1.19X.10³lb/m,what is the mass (in kg) of a cable made of six strands of optical fiber, each long enough to link New York and Paris (8.84X.10³km)?

A chemist mixes two liquids, A and B, to form a homogeneous mixture. The densities of the liquids are 2.0514 g/mL for A and 2.6678 g/mL for B. When she drops a small object into the mixture, she finds that the object becomes suspended in the liquid; that is, it neither sinks nor floats. If the mixture is made of 41.37 percent A and 58.63 percent B by volume, what is the density of the metal? Group of answer choices 2.413 g/mL 1.753 g/mL 2.691 g/mL 2.015 g/mL 1.913 g/mL

The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.162g/mL. A 4.034g glass fragment was recovered from a suspect's clothing. When the fragment was placed into a graduated cylinder filled with water, 1.63mL of the water was displaced. Calculate the density of the glass fragment.

Water has a density of 0.96 mL-1 at its boiling point of 100 C under standard atmospheric pressure. The density of water vapor is about 1600 times less than the density of water under the same conditions. If a 1.00 L beaker of water was converted into water vapor at 100 C under standard atmospheric pressure, what would the volume (in L) of the water vapor be?

A sample of metal has a mass of 21.49g, and a volume of 6.55 mL. What is the density of this metal?  density:? g/cm^3
