How many carbon atoms are in 3 grams?
Well… (3 grams of carbon) x (1 mole of carbon/12 grams ) = 3/12 = 1/4 of a mole of carbon. Then… ( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms.
How do you calculate atoms?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
How many atoms are in 16g of oxygen?
3.01 × 10 23D. 3.01 × 1023.
How many oxygen molecules are in 3.00 moles of oxygen?
Explanation: A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .
How many oxygen atoms are there in 18 gram of water?
– As in one mole of water there are6.022×1023 molecules, that's how the mole was defined. – And as the chemical formula for water is H2O, and one mole of water corresponds to one mole of oxygen atoms. Hence, there will be 6.022×1023 oxygen atoms in one mole, or we can say 18 g of water.
How do you calculate 8g of o2?
- The Molecular mass of Oxygen (O2) is 32 g.
- Number of Moles in 8g of Oxygen = 8/32 = 0.25 moles.
- Therefore, the number of particles/molecules = 0.25 × 6.022 × 1023 = 1.5055 × 1023 molecules = 1.51 × 1023
How do you find atoms from grams?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
How many oxygen atoms are in the formula?
two oxygen atoms The symbol for the element oxygen, O, represents both the element and one atom of oxygen. A molecule of oxygen, O2, contains two oxygen atoms; the subscript 2 in the formula must be used to distinguish the diatomic molecule from two single oxygen atoms.
How do you know how many oxygen atoms are in a compound?

How do you calculate number of atoms?
# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.

How do you find the number of atoms in a gram?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.
How many atoms are there in 32g of oxygen?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
How many atoms of oxygen are in 3.0 moles of oxygen atoms?
Explanation: 1 mole of O₂ contains 6.022 × 10²³ atoms. Thus, 3 moles O₂ would contain 3 × 6.022 × 10²³ atoms. Therefore, 3 moles of O₂ contain 18.066 × 10²³ atoms.
