Very close to 2. If it's all carbon-12, it will be exactly two, but there's enough carbon-13 in natural abundance carbon (about one part in a hundred) to bring the average Atomic Mass up to something like 12.011.

How many carbon atom are in 5.60 g of glucose?
5.60 g C6H12O6 (1 mole C6H12O6/180.156 g)(6 moles C/1 mole C6H12O6)(6.022 X 1023/1 mole C) = 1.12 X 1023 atoms of carbon ======================
What statement about krypton is not true A its molar mass is 83.798 g per mol Kr B Its atomic number is 36 C one mole of krypton atoms has a mass of 41 point 90g D it is a noble gas?
Statement C is not true. One mole of krypton atoms has a mass of approximately 83.798 g, not 41.90 g.
What formulas give atom to atom mole to mole and atom to molecule ratios?
The atom to atom mole ratio is determined by the coefficients of the balanced chemical equation. For example, in the equation 2H₂ + O₂ → 2H₂O, the atom to atom mole ratio of hydrogen to oxygen is 2:1. The atom to molecule ratio is based on the number of atoms in each species and how they combine to form molecules. For example, in the equation 2H₂ + O₂ → 2H₂O, the atom to molecule ratio of hydrogen to water molecules is 4:2 or 2:1.
What is the mass of six helium atoms?
32 g
How do you get a chemistry mole?
A chemistry mole is a unit used to express amounts of substance. To calculate the number of moles, you divide the given mass of the substance by its molar mass (grams per mole). This can help in performing calculations involving chemical reactions and stoichiometry.
How many Atoms are in 169g of c?
169 g C x 1 mole C/12.011 g x 6.02x10^23 atoms/mole = 8.47x10^24 atoms
How many atoms are in 24 grams of carbon?
There are 2.45 x 10^23 carbon atoms in 24 grams of carbon.
How many atoms of carbon are in a pure sample of carbon having a mass of 72.0 g?
There are 6.022 x 10^23 atoms in 1 mole of carbon. The molar mass of carbon is 12 g/mol. Therefore, in 72.0 g of carbon, there are (72.0 g / 12 g/mol) * 6.022 x 10^23 atoms = 3.61 x 10^24 atoms of carbon.
How many carbon atoms are contained in 85.9 g of carbon?
There are 7.16 moles of carbon in 85.9 g of carbon (85.9 g / 12 g/mol). Since there are 6.022 x 10^23 atoms in 1 mole of carbon, the number of carbon atoms in 85.9 g is 4.31 x 10^24 atoms.
How many atoms are in a 12 g of C?
To find the number of carbon atoms in 12 g of carbon (C), you first need to calculate the number of moles of carbon (C) in 12 g using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23) to determine the number of atoms in that many moles of carbon (C).
How many moles of C do you have in the CO2?
In one mole of CO2, there is one mole of carbon (C). So if you have 1 mole of CO2, you have 1 mole of carbon.
How many carbon atom are in 5.60 g of glucose?
5.60 g C6H12O6 (1 mole C6H12O6/180.156 g)(6 moles C/1 mole C6H12O6)(6.022 X 1023/1 mole C) = 1.12 X 1023 atoms of carbon ======================
What is the mass of atoms in grams of 1.02X10 to the 24 atoms Mn?
To find the mass of 1.02×10^24 atoms of Mn, you need to calculate the atomic mass of Mn from the periodic table (54.938045 g/mol). Then, divide the number of atoms by Avogadro's number to get moles, and finally multiply by the atomic mass to get the mass in grams. The mass of 1.02×10^24 atoms of Mn would be approximately 94.64 grams.
How many grams are in 1 mol nahco3?
1 mole of NaHCO3 Na = 1 * 22.99 g = 22.99 g H = 1 * 1.01 g = 1.01 g C = 1 * 12.01 g = 12.01 g O = 3 * 16.00 g = 48.00 g Total = 84.01 g There are 84.01 grams in one mole of NaHCO3.
What statement about krypton is not true A its molar mass is 83.798 g per mol Kr B Its atomic number is 36 C one mole of krypton atoms has a mass of 41 point 90g D it is a noble gas?
Statement C is not true. One mole of krypton atoms has a mass of approximately 83.798 g, not 41.90 g.
How many iron atoms are contained in 354 g of iron?
There are approximately 3.25 x 10^24 iron atoms in 354 g of iron. This calculation is done by converting the mass of iron to moles using the molar mass of iron, and then using Avogadro's number to convert moles to atoms.
What formulas give atom to atom mole to mole and atom to molecule ratios?
The atom to atom mole ratio is determined by the coefficients of the balanced chemical equation. For example, in the equation 2H₂ + O₂ → 2H₂O, the atom to atom mole ratio of hydrogen to oxygen is 2:1. The atom to molecule ratio is based on the number of atoms in each species and how they combine to form molecules.
