Chapter 1, Problem 1.93E

the diameter of a 16-gauge wire has a diameter of 0.05082 in. what length of wire in meter is found in a 1.60 lb spool of 16-gauge copper wire. desity of copper is 8.92g/cm^3

A mass of 1.0×10−5 μkgμkg is the same as   1.0×10−8 gg. 1.0 mgmg. 1.0×10−11 gg. 1.0 kgkg.

a student has been given a solid sample and asked to calculate its density. She measured the mass of the solid sample and recorded it on her data sheet as 4.528g. She recorded the initial volume as 4.7 mL and final volume as 6.2 mL. What is the density of the sample

What is the density in g/cm3 ? mass= 0.9811gvolume= 376.8mm

A glass cylinder contains four liquid layers: mercury (d = 13.6 g/mL), chloroform (d = 1.49 g/mL), water (d = 1.00 g/mL), and ether (d = 0.708 g/mL). If a marble (d=2.7 g/mL) is dropped into the cylinder, where does it come to rest? A) on top of the ether layer B) on top of the water layer C) on top of the chloroform layer D) on top of the mercury layer E) on the bottom of the cylinder

a sample od copper  has mass of 2.45 mg and avolume of 2.733* 108 cubic micro meter. calculate the density of copper in g/cm3

1.  A graduacted cylinder was filled with water until the voulume until the voulme read 55.0 mL. A rubber stopper was weighed and determined to have a mass of 6.782 g. The rubber stopper was carefully lowered into the graducated cylinder, and the volume was measure to be 60.6 mL. a) Calculate the denisty of the rubber stopper.   2. A 0.825 g pice of copper foil (d = 8.94 g/cm^3) measures 5.00 cm x 7.50 cm. a) Caculate the volume of the copper foil b) Caculate the thickness of the copper foil.

Use ?=1.00 g/mLd=1.00 g/mL as the density of water. volume:   mLmL How much would the beaker and its contents weigh if it was completely filled with mercury? The density of mercury is ?=13.5 g/mL.d=13.5 g/mL. total mass:

At 20oC 25.0 ml of concentrated nitric acid solution was found to have a mass of 32.503 g. What is the calculated density of this solution at 20oC? Show your calculation set-up and result using correct significant figures and proper units.              Volume of Nitric acid = 25.0 ml                  Mass of nitric acid = 32.503 g     Density = mass of substance                     Density= Mass of nitric acid                  volume of substance                                  volume of nitric acid                                   = 32.503g                                   25 .0mL                                    =  1.30g/mL  (3 sig figures)     Using the calculated density of the solution from above, what is the mass of 150 ml. of the solution? Again show your solution set-up with correct significant figures and units.
