Select the correct option for decreasing order of number of atom 1)2gm...
Decreasing order of number of atoms:
1. 16 gm sulphur:
- Atomic mass of sulphur = 32 g/mol
- Number of moles in 16 gm of sulphur = 16/32 = 0.5 mol
- Number of atoms in 16 gm of sulphur = 0.5 mol * 6.022 x 10^23 atoms/mol = 3.011 x 10^23 atoms
2. 31 gm of phosphorus:
- Atomic mass of phosphorus = 31 g/mol
- Number of moles in 31 gm of phosphorus = 31/31 = 1 mol
- Number of atoms in 31 gm of phosphorus = 1 mol * 6.022 x 10^23 atoms/mol = 6.022 x 10^23 atoms
3. 4 gm of oxygen:
- Atomic mass of oxygen = 16 g/mol
- Number of moles in 4 gm of oxygen = 4/16 = 0.25 mol
- Number of atoms in 4 gm of oxygen = 0.25 mol * 6.022 x 10^23 atoms/mol = 1.506 x 10^23 atoms
4. 2 gm hydrogen:
- Atomic mass of hydrogen = 1 g/mol
- Number of moles in 2 gm of hydrogen = 2/1 = 2 mol
- Number of atoms in 2 gm of hydrogen = 2 mol * 6.022 x 10^23 atoms/mol = 1.2044 x 10^24 atoms
Therefore, the decreasing order of the number of atoms is:
1. 2 gm hydrogen
2. 31 gm of phosphorus
3. 16 gm sulphur
4. 4 gm of oxygen
1. 16 gm sulphur:
- Atomic mass of sulphur = 32 g/mol
- Number of moles in 16 gm of sulphur = 16/32 = 0.5 mol
- Number of atoms in 16 gm of sulphur = 0.5 mol * 6.022 x 10^23 atoms/mol = 3.011 x 10^23 atoms
2. 31 gm of phosphorus:
- Atomic mass of phosphorus = 31 g/mol
- Number of moles in 31 gm of phosphorus = 31/31 = 1 mol
- Number of atoms in 31 gm of phosphorus = 1 mol * 6.022 x 10^23 atoms/mol = 6.022 x 10^23 atoms
3. 4 gm of oxygen:
- Atomic mass of oxygen = 16 g/mol
- Number of moles in 4 gm of oxygen = 4/16 = 0.25 mol
- Number of atoms in 4 gm of oxygen = 0.25 mol * 6.022 x 10^23 atoms/mol = 1.506 x 10^23 atoms
4. 2 gm hydrogen:
- Atomic mass of hydrogen = 1 g/mol
- Number of moles in 2 gm of hydrogen = 2/1 = 2 mol
- Number of atoms in 2 gm of hydrogen = 2 mol * 6.022 x 10^23 atoms/mol = 1.2044 x 10^24 atoms
Therefore, the decreasing order of the number of atoms is:
1. 2 gm hydrogen
2. 31 gm of phosphorus
3. 16 gm sulphur
4. 4 gm of oxygen
