The density of glycerin is Grams/ 1.26 centimeter. How many pounds/ foot^3 is this? Use the conversion rates of 454 grams/ 1 pound and 28,317 centimeters^3 / 1 foot^3 Express your answer to the correct number of significant figures.
The density is ???
pounds/
foot3

78.6 lb/ft³  

Step-by-step explanation:

Let's do this in steps.

1. Convert grams to pounds

D = (1.26 g/1 cm³) × (1 lb/454 g)

  = 2.775 × 10⁻³ lb/cm³

2. Convert cubic centimetres to cubic feet

D = (2.775 × 10⁻³ lb/1 cm³) × (28 317cm³/1 ft³)

  = 78.6 lb/ft³

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
