How many grams of carbon are in 0.500 mole of carbon?

6.0055 grams of Carbon

Explanation:

If you look in the periodic table at carbon you can see the atomic molecular mass of 12.011 or something around 12. This number also represents the number of grams in one mole of a substance. So in this case, there are 12ish grams in one mole of carbon atoms. 0.5 moles is just half of a mole. So, 12 grams for one mole divided by 2 would be around 6 grams of carbon atoms for half a mole (or 6.0055 grams considering that one mole is 12.011 grams of carbon atoms)

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

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.
