The questions asks how many moles of carbon atoms.
Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.
How many atoms are in 36 grams of Carbon?
[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
3 grams carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C)(1 mole C atoms/6.022 X 10^23)
= 0.25 moles of carbon atoms
-------------------------------------
( as you may see this is a formal set-up and Alessandro's number is over itself in a form of one, so the first ratio, mole/gram, is all that is needed here )
the formula for the moles of a substance is mol= grams/ grams per mol the grams per mol of carbon is 12.01 grams per mol, so... mol= 360g/12.01 grams per mol = 27.7 mol
Moles = mass / relative molecular mass. 360 / 1 + 1 + 16 = 20 moles
63,60 g sample of carbon is equivalent to 5,296 moles.
5.296 grams per mol of Carbon
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
1 mole of any substance contains 6.02x1023 representative particles. That is called Avogadro's number, and it's one of the most important constants in science. So, 3 moles of carbon would be 3 times that, which would be 18.06x1023, which simplifies to 1.806x1024 atoms.
5 moles carbon? 5 grams carbon? Both done. 5 moles carbon (6.022 X 1023/1 mole C) = 3.0 X 1024 atoms carbon =================== 5 grams carbon (1 mole C/12.01 grams)(6.022 X 1023/1 mole C) = 2.5 X 1023 atoms carbon ==================== your choice
The molecular weight of Novocaine/Procaine (C12H21N2O2Cl) is 236.3 grams per mole. Each molecule of Novocaine contains 12 moles of carbon (C). 1.574 grams of Novocaine equals .006661 moles. Therefore, .07993 moles of C are to found in this sample size.

# of moles = Mass÷ Formula weight Example: 6 grams of Carbon atoms Carbon has an atomic mass of 12 grams so according to the Equation # of moles = 6÷ 12 = 0.5 moles For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams. Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454 moles So for sodium, # of moles = 45.48 g ÷ 22.99g/mole = moles You divide!
There are 24 moles of Carbon (C) in 2 moles of table sugar (sucrose)
There are 9.33 moles of carbon in 5.62 atoms of carbon.
6,1x10-3 moles of carbon 36,7350592277.1020 atoms.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
30.0 grams carbon (1 mole C/12.01 grams) = 2.50 moles carbon ===============
About one half mole. 6 grams carbon (1 mole C/12.01 grams) = 0.4996 moles of carbon --------------------------------- that is, 0.5 moles carbon ---------------------------------
