How many moles of carbon atoms are there in 3 grams of carbon?

Answer 1

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

Answer 2

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 )

Answer 3

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

Answer 4

Moles = mass / relative molecular mass. 360 / 1 + 1 + 16 = 20 moles

Answer 5

63,60 g sample of carbon is equivalent to 5,296 moles.

Answer 6

5.296 grams per mol of Carbon
