What is a mole (chemistry)?

Question

what is one mole of c02 equal to? oxygen? ammonia? i don really understand it . thanks!!!!!

Answer 1

there are a lot of formulas, wherein you can compute for mole..

but first, let's define what a mole is..

mole is a heap or file of any chemical specie

mole is the International System unit of substance amount: the basic International System unit of amount of a substance  (forom encarta dictionary)

to compute for mole:

take note: symbol for mole is 'n'

n= m/M where n=mole, m=mass, and MW=molecular weight

n=N/NA  where, n=mole, N=number of atoms and ;

NA (A written in subscript)=Avogadro's constant (6.023 x 10 to the 23rd power atoms/mole)

about your problem, i guess you need to solve for the molecular weight of the compound

cO2 (carbon dioxide) = 12 + 16(2)

= 12 + 32

= 44 g/mole

check the periodic table for the atomic weight,

hoping it can help u

Answer 2

A mole is 6.022 * 10^23 of a quantity.  A mole is a useful measure in that one mole is equal to the molecular weight of the substance in grams.  For example, a mole of ammonia weighs 17g.

Answer 3

A mole is just the name given for a certain number of things.  Just as a dozen donuts means 12 donuts, a mole of donuts means 6.022x10^23 donuts.  That's obviously a huge number, and it doesn't mean much in terms of everyday objects like donuts...but when you're talking about extremely small things like molecules, it makes more sense.

For example, consider a mole of water (H2O) molecules [1,2]:

m(mole H2O) = 2m(mole H) + m(mole O)

= 2(1.008 g/mole) + 15.99 g/mole = 18.006 g/mole

= 0.018 kg/mole

ρ = m/V → V = m/ρ

V = (0.018 kg) / (1000 kg/m³) = 1.8x10^-5 m³

= 18 cm³

That's about half of a mouthful of water [3].

Answer 4

a mole of CO2 is equal to

2 atoms of oxygen + 1 atom of carbon = 1 mole of carbon dioxide !

i hope this`ll help u

see ya

Answer 5

A mole is 6.022 x 10^23 atoms or molecules.  If an atom has one proton, like hydrogen, it has 1 gram per mole, or 1 gram of hydrogen would be 6.022 x 10^23 atoms.  CO2 has 2 oxygen atoms - atomic mass 16, and one carbon atom - atomic mass 12, so 16 + 16 + 12 = 44 grams per mole of CO2.  The heavier an atom or molecule is, the larger the mass will be to make up that large number of atoms or molecules 6.022 x 10^23, called Avogadro's number.

Answer 6

A mole is just a specific number (6.02214×10^23).  One mole of c02 is 6.02214×10^23 c02 molecules. One mole of oxygen is 6.02214×10^23 oxygen atoms. One mole of ammonia is 6.02214×10^23 ammonia molecules. It is convenient to say "I have one mole of c02" instead of "I have 6.02214×10^23 c02 molecules", but they are identical.

Answer 7

oooh I hated Chemistry take Biology!!! 4get Chemistry and Physics even exist!!! but use the mole formula u can get it from google type in your question steps should b on there
