To convert atoms to grams, you need to take the number of atoms, divide it by Avogadro's Constant, then multiply it by the Atomic Mass.
Atoms ÷ (6.02 × 1023) × Atomic mass = Mass in grams
1.505 × 1023 ÷ (6.02 × 1023) × 12.0 = 3.00 grams Carbon

How many atoms of carbon and hydrogen does decane have in it?
Decane has 10 carbon atoms and 22 hydrogen atoms.
How many atoms in 12 grams of carbon?
Atomic mass of carbon: 12.0 grams12.01 grams C × (6.02 × 1023 atoms) / (12.0 grams) = 6.03 × 1023 atoms of CarbonNote 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.
How many moles of carbon atoms are there in 3 grams 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
How many atoms of carbon are in 10.0 grams of carbon?
The gram atomic mass of carbon is 12.011. Therefore, 1.1 grams constitutes 1.1/12.011 or about 0.0908 moles of carbon. The number of atoms is then 0.0908 X Avogadro's Number or 5.5 X 1022 atoms, to the justified number of significant digits.
How many atoms are in Carbon?
12 g of carbon will have 6.023 x 1023 atoms of carbon
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
What is the mass in grams of 100 atoms of the carbon 12 isotope?
100 atoms of C-12(12g/6.022x10^23) = 1.993x10^-21g
What is 10 percent of 1505 gross earning?
10% of 1505 = 10% * 1505 = 0.1 * 1505 = 150.5
What are the steps needed to convert the number of atoms to the mass of an elementt?
Let us use carbon in this example. Carbon is 12.01 grams per mole. Let us say we have 2.36 X 10^22 atoms of carbon 2.36 X 10^22 atoms carbon (1mole Carbon/6.022 X 10^23)(12.01 grams Carbon/1mol Carbon ) = 0.47 grams Carbon. 6.022 X 10^23 is Avogadro's number and is a constant that is a mole of anything. Just as a dozen eggs is always 12 eggs.
Why is the mass in atomic mass units of a carbon-12 atom reported as 12.011?
This is because one mole of atoms (6.02 x 10^23 atoms) weighs 12.011g.
What is the molecular mass of substance each molecule of which contain 4 carbon atoms and 10 hydrogen atoms.?
This would be C4H10 and the molecular mass is (12x4) +(1x10) = 48 + 10 = 58g/mole.
How many carbon atoms are in 0.136g of carbon?
We take the atomic mass of carbon to be 12.0Amount of carbon in 0.136g pure sample = 0.136/12.0 = 0.0113 The Avogadro's number is 6.02 x 10^23 Number of carbon atoms = 0.0113 x 6.02 x 10^23 = 6.82 x 10^21
How many atoms of carbon are in a pure sample of carbon having a mass of 72.0 g?
72.0 grams Carbon (1 mole C/12.01 grams)(6.022 X 10^23/1 mole C) = 3.61 X 10^24 atoms of carbon
What is the mass in grams of 4350000 atoms of carbon?
Not that much!! 4350000 atoms Carbon (1 mole C/6.022 X 10^23)(12.01 grams/1 mole C) = 8.675 X 10^-17 grams
What the mass in grams of 7.40 x 1017 atoms of carbon?
The gram atomic mass of carbon is 12.011 grams. This, by definition, is the mass of Avogadro's number of carbon atoms. Regarding the specified number of atoms as 7.40 X 1017, their mass is accordingly 12.011(7.40 X 1017)/(6.022 X 1023) = 1.48 X 10-5, to the justified number of significant digits (limited to 3 by "7.40".)
How many atoms of carbon and hydrogen does decane have in it?
Decane has 10 carbon atoms and 22 hydrogen atoms.
What is the mass of 2.0 moles of carbon?
First, get the molar mass of CCl4, which is carbon tetrachloride. According to the periodic table, carbon has an atomic mass of 12 and chlorine is 35.5, but there's 4 of them, so multiply that by 4. 35.5(4)+12=154grams/mole. If you have 2.5 moles, then it's 154x2.5=305 grams.
