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 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 is the mass of 7.8 x 1018 carbon atoms?
3.011 x 1023 atoms of carbon will weigh about 6 grams One mole of carbon atoms weighs 12.011 grams, and there are 6.022 x 1023 atoms in a moles. So you have half as many atoms, so the mass would be half as much or 6.0055 grams to be precise.
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.
How many neutrons does the isotope carbon have?
Most carbon atoms have 6 neutrons, but a small fraction of them have 7 neutrons (to make carbon-13 isotope atoms) or 8 neutrons to make carbon-14 isotopes. Radioactive carbon atoms with other numbers of neutrons can be made in nuclear reactions.
What is the mass of a mole of isotope carbon-12?
According to the definition by IUPAC, the mass of a mold of carbon-12 isotope is exactly 12.0000 g.

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.
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! :)
If the atomic mass of a carbon is 12 amu 1 mole of pure carbon will have a mass of?
1 mole of carbon atoms will have a mass of 12 grams (atomic mass in amu is numerically equivalent to the molar mass in grams per mole).
What relationships are needed to convert 1.5 grams of carbon to the number of carbon atoms?

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.
What isotope of carbon has been chosen as the reference isotope for atomic mass units?
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.
