What is 6.5 moles of carbon in grams?

To do this, you need to know the atomic weight of the element you're dealing with, found on any periodic table. The atomic weight is the mass in grams of the element in one mole - this will provide you with a conversion factor. So take the measurement in moles and multiply it by the atomic weight to convert to grams. Really what you're doing is dividing the number by 1 mole, and multiplying it by the equivalent of one mole, the atomic weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about 78 grams C.


Which group in the periodic table does not form compounds?

The group on the far right of the periodic table of elements will not bond to form compounds. These are the Noble Gases aka Inert Gases and are the elements of Group 18, which includes helium, neon, argon, krypton, xenon, radon, and element 118. I think that's all of them. I am not 100% confident that this list is entirely inclusive so there may be some other element(s) that do not form compounds. I am sure however that Noble Gases do not react due to the fact that their electron shells are full.


How many moles are in 97.2 grams of boron?

To do this, you need to know the atomic weight of the element you're dealing with, found on any periodic table. The atomic weight is the mass in grams of the element in one mole - this will provide you with a conversion factor.

Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the atomic weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about 8.99 moles B.

How did plutonium get its name?

suggested that element 94, being the next element in the series, be named for what was then considered the next planet, Pluto.[4][note 2] Seaborg originally considered the name "plutium", but later thought that it did not sound as good as "plutonium."[33] He chose the letters "Pu" as a joke, which passed without notice into the periodic table.[note 3] Alternate names considered by Seaborg and others were "ultimium" or "extremium" because of the now-discredited belief that they had found the last possible element on the periodic table.[34] suggested that element 94, being the next element in the series, be named for what was then considered the next planet, Pluto.[4][note 2] Seaborg originally considered the name "plutium", but later thought that it did not sound as good as "plutonium."[33] He chose the letters "Pu" as a joke, which passed without notice into the periodic table.[note 3] Alternate names considered by Seaborg and others were "ultimium" or "extremium" because of the now-discredited belief that they had found the last possible element on the periodic table.[34]
