What is the number of oxygen atom in 32 g of gas (oxygen is equal to 16 and avocado number is equal to 6 * 10 ^ 23
To find the number of oxygen atoms in 32 g of gas, we need to first determine how many moles of oxygen are present in 32 g.
The molar mass of oxygen is 16 g/mol. Therefore, the number of moles of oxygen in 32 g is:
32 g / 16 g/mol = 2 moles
Since 1 mole of a substance contains Avogadro's number of atoms (6 x 10^23), 2 moles of oxygen contain:
2 moles x 6 x 10^23 atoms/mole = 1.2 x 10^24 oxygen atoms
Therefore, there are 1.2 x 10^24 oxygen atoms in 32 g of gas.
