How many atoms of carbon (c,12.01 g/mol) are in a diamond with a mass of 0.568 g?

2.85 × 10^22. A diamond with a mass of 0.568 g contains

2.85 × 10^22 atoms C.

Diamond is a form of pure carbon.

a)Convert grams of C to moles of C

Moles of C = 0.568 g C × (1 mol C/12.01 g C) = 0.047 29 mol C

b)Convert moles of C to atoms of C

Atoms of C = 0.047 29 mol C × (6.022 × 10^23 atoms C)/(1 mol C)

= 2.85 × 10^22 atoms C

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
