What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
Most calcium atoms have an atomic number of 20 and a mass number of 40 but some calcium atoms have a mass number of 48 What word could you use to describe these two kinds of calcium atoms?
Isotopes.
How many moles are in hydrogen atoms?
divide the mass of the hydrogen by the molar mass.
How many atoms are in 10g of Fe?
Molar mass of iron = 55.845g/mol (atomic weight in grams/mol) 1mol Fe atoms = 6.022 x 1023 atoms Fe 10g Fe x 1mol/55.845g x 6.022 x 1023 atoms/mol = 1.078 x 1023 atoms
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.
The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
the number of atoms is equal to the mass of the sample divided by its molar mass times one mole 11.74g / 58.69g/mol * 6.02*1023 atoms/mol = 1.2*1023 atoms approximately
How many atoms are in 125 grams of Calcium?
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
What is the mass in grams of 6.022 x 1023 N atoms of mass 14.01 amu?
The molar mass of any element is its atomic weight (amu) in grams, and 1 mol of any element is 6.022 x 1023 atoms. Therefore, the mass in grams of 6.022 x 1023 atoms of N = 14.01g N.
How many atoms are in 1.0g of hydrogen atoms each mass 1.0amu?
6.023 x 1023 atoms
What is the mass in grams of 6.022 x 1023 atoms of 12C?
12
How many atoms are in a 2.5 mole sample of calcium?
450.3915Calcium Carbonate (CaCO3) has a molar mass of 100.087 g/mol.4.5 mol * 100.087 g/mol = 450.3915 (because the mol's cancel leaving you with 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 sucrose table sugar?
1 mole has 12.01 grams and has 6.022 x 1023 atoms. There are 6 carbon atoms in a glucose molecule so that times six would give you a total of 72.06 grams out of the 180.156 (molar mass for glucose). Carbon makes up about 40 percent of the total glucose mass so the final answer would be it would be around 2.4088 x 1023 atoms of carbon in one gram. Times that by 4 and you'll get 9.6352 x 1023 atoms of carbon in four gram of glucose.
What is the mass of 4.21 x 10 to the 23rd atoms of P?
4.21 × 1023 atoms ÷ (6.02 × 1023 atoms) × 30.97 grams = 21.66 grams P
What is the mass of 8.90 x 1023 lead atoms?
8.90 X 1023 lead atoms (1 mole Pb/6.022 X 1023)(207.2 grams/1 mole Pb) = 306 grams of lead =============
How do you find the mass of an atom with only the molar mass given?
Molar mass of an element is the atomic weight on the periodic table in grams. 1 mole of atoms of an element is 6.022 x 1023 atoms. To find the mass of one atom of an element, divide the element's molar mass by 6.022 x 1023 atoms.Example:Sodium, Na, has a molar mass of 22.989770g/mol (atomic weight in grams)1 mole Na atoms = 6.022 x 1023 atomsSolution:22.989770g/mol x 1mol/6.022 x 1023 atoms = 3.818 x 10-23g/atom
