A mole of Au
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
gold, as it has a higher molar mass
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! :)
The atomic mass of Cd is 112 This means that the mass of 1 mole of Cd atoms is 112g.
Gold, as it has the higher molar mass.
1 mole of iron atoms has the greatest mass - 55,845 g.
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.
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
Because the sum of protons, neutrons and electrons masses in sulfur atom is higher than in a carbon atom.
Yes. One mole (6.022x1023) of hydrogen atoms would have a mass of about 1g.
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
gold, as it has a higher molar mass
is it true the size of a mmole of atoms has a reasonable mass
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! :)
Thast is one mole. 26.98 grams/per mole is the mass.
