Atomic Mass of carbon: 12.0 grams
12.01 grams C × (6.02 × 1023 atoms) / (12.0 grams) = 6.03 × 1023 atoms of Carbon
Note that one mole of any substance is Avogadro's constant (6.02 × 1023) and that one mole of Carbon is 12.0 grams. So if you have 12.01 grams of carbon (roughly one mole) you should get about Avogadro's constant.
There are approximately 6.022 x 10^23 atoms in 12 grams of carbon-12 (Avogadro's number). Since carbon-13 has one more neutron, it will have a slightly lower number of atoms than carbon-12 per unit mass. Therefore, there will be slightly fewer atoms in 9.00 grams of carbon-13 compared to carbon-12, but the difference is negligible.
There are 1.9 grams of Carbon. The molar mass of carbon is approximately 12 grams per mole. This means there are ~0.158 moles of carbon. Since 1 mole of carbon contains Avogadro's number of atoms (~6.022 x 10^23 atoms), then 0.158 moles would contain ~9.53 x 10^22 atoms.
That is about the mole definition of Avogadro's number, so. 6.022 X 10^23 atoms of carbon
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
1.7 grams * (1mole/ 12.011 grams) * (6.023x 10^23 atoms/ 1 mole) =8.525 * 10^ 22 atoms carbon round to 2 sig. figs
The molar mass of carbon-12 (12C) is 12 g/mol. Therefore, one mole of carbon-12 atoms has a mass of 12 grams. Since there are 6.022 x 10^23 atoms of carbon-12, the mass of 6.022 x 10^23 atoms of carbon-12 is also 12 grams, based on Avogadro's number and the molar mass of carbon-12.
There are approximately 6.022 x 10^23 atoms in 12 grams of carbon-12 (Avogadro's number). Since carbon-13 has one more neutron, it will have a slightly lower number of atoms than carbon-12 per unit mass. Therefore, there will be slightly fewer atoms in 9.00 grams of carbon-13 compared to carbon-12, but the difference is negligible.
One mole of carbon-12 with a mass of 12 grams contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Therefore, in 6 grams of carbon-12, there will be approximately 3.011 x 10^23 atoms.
This is half a mole. Thus there will be half the Avogadro number of atoms, i.e. approximately 3.011 times 10 to the twenty third power.
There are more carbon atoms in 48 grams of CO2 than in 12 grams of diamond
mole
There are 1.9 grams of Carbon. The molar mass of carbon is approximately 12 grams per mole. This means there are ~0.158 moles of carbon. Since 1 mole of carbon contains Avogadro's number of atoms (~6.022 x 10^23 atoms), then 0.158 moles would contain ~9.53 x 10^22 atoms.
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)
