One mole of N2 molecules.
One mole of N2 molecules is equal to 6.022 x 10^23 N2 molecules. This is also known as Avogadro's number.
Find number of atoms of carbon present in 24G of carbon
To calculate the number of atoms of carbon present in 24 g of carbon, we need to use Avogadro's number and the atomic mass of carbon.
The atomic mass of carbon is 12.01 g/mol, which means that one mole of carbon has a mass of 12.01 grams and contains 6.022 x 10^23 atoms.
To find the number of moles of carbon in 24 g, we divide 24 g by the atomic mass of carbon:
Number of moles of carbon = 24 g / 12.01 g/mol = 1.998 moles
Therefore, the number of atoms of carbon in 24 g is:
Number of atoms = 1.998 moles x 6.022 x 10^23 atoms/mol = 1.204 x 10^24 atoms
So there are approximately 1.204 x 10^24 atoms of carbon in 24 g of carbon.
Find number of atoms
In 17.0. Mol of Germanium
To calculate the number of atoms in 17.0 moles of Germanium, we can use Avogadro's number:
1 mole of Germanium = 6.022 x 10^23 atoms of Germanium
17.0 moles of Germanium = (17.0 mol) x (6.022 x 10^23 atoms/mol)
= 1.02574 x 10^25 atoms
Therefore, there are approximately 1.02574 x 10^25 atoms of Germanium in 17.0 moles of this element.
Calculate the number of atoms in 0.0082 gram of gold.
To calculate the number of atoms in 0.0082 gram of gold, we need to use the atomic mass of gold and Avogadro's number.
The atomic mass of gold is 196.97 g/mol, which means that one mole of gold has a mass of 196.97 grams and contains 6.022 x 10^23 atoms.
First, we need to find the number of moles of gold in 0.0082 grams:
Number of moles of gold = 0.0082 g / 196.97 g/mol = 4.16 x 10^-5 mol
To find the number of atoms of gold, we multiply the number of moles by Avogadro's number:
Number of atoms = 4.16 x 10^-5 mol x 6.022 x 10^23 atoms/mol = 2.50 x 10^18 atoms
So there are approximately 2.50 x 10^18 atoms of gold in 0.0082 grams of this element.
