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".)

To find the mass of 7.40 x 10^17 carbon atoms, you need to use the molar mass of carbon, which is approximately 12.01 g/mol. To calculate the mass, first find the number of moles by dividing the number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol), then multiply by the molar mass. Your result will be around 1.48 x 10^4 grams.

What is the mass in grams of 6.022 x 1023 atoms of 12C?
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.
What is the mass in grams of 4350000 atoms of carbon?
To find the mass of 4350000 atoms of carbon, first calculate the molar mass of carbon (12.01 g/mol). Then, divide the molar mass by Avogadro's number to find the mass of one carbon atom. Finally, multiply the mass of one carbon atom by 4350000 to find the total mass of 4350000 carbon atoms.
Does mole of carbon atoms have a different mass than a mole of sulphur atoms?
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
What is the mass of one mole of carbon 13 atoms?
The mass of one carbon-13 atom is approximately 13 atomic mass units (u). Therefore, the mass of one mole of carbon-13 atoms is 13 grams.
How many carbon atoms are in 2 grams of 1 carat diamond?
There are about 1.092 x 10^21 carbon atoms in 2 grams of 1 carat diamond. This is calculated based on the molar mass of carbon and Avogadro's number.
How many grams of sodium carbonate contain 1.773 x 1017 carbon atoms?
To find how many grams of sodium carbonate contain 1.773 x 10^17 carbon atoms, you need to consider the molar ratio. Sodium carbonate (Na2CO3) has 1 carbon atom per molecule. Calculate the molar mass of Na2CO3, then use Avogadro's number to convert the number of carbon atoms to moles, and finally to grams.

What is the mass in grams of 6.022 x 1023 atoms of 12C?
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.
How many atoms of carbon are in 2.50 grams of theobromine C7H8N4O2?
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
What is the mass in grams of 4350000 atoms of carbon?
To find the mass of 4350000 atoms of carbon, first calculate the molar mass of carbon (12.01 g/mol). Then, divide the molar mass by Avogadro's number to find the mass of one carbon atom. Finally, multiply the mass of one carbon atom by 4350000 to find the total mass of 4350000 carbon atoms.
What is the mass of 1 mole of carbon atom?
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! :)
What relationships are needed to convert 1.5 grams of carbon to the number of carbon atoms?
To convert 1.5 grams of carbon to the number of carbon atoms, you would need to use Avogadro's number, which is the number of atoms in one mole of a substance (6.022 x 10^23 atoms/mol), and the molar mass of carbon (12.01 g/mol). By dividing the given mass of carbon (1.5 g) by the molar mass of carbon, you can convert the grams to moles, and then use Avogadro's number to calculate the number of carbon atoms.
What is the mass of 7.8 x 1018 carbon atoms?
The molar mass of carbon is approximately 12 g/mol. To find the mass of 7.8 x 10^18 carbon atoms, we first need to convert the number of atoms to moles by dividing by Avogadro's number (6.022 x 10^23 atoms/mol) and then multiply by the molar mass of carbon. The mass of 7.8 x 10^18 carbon atoms is approximately 1.6 x 10^-5 grams.
What is the mass of 1.505 x 10²³ carbon atoms?
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 grams1.505 × 1023 ÷ (6.02 × 1023) × 12.0 = 3.00 grams Carbon
How many atoms are in 1.9 g Carbon?
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.
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
