Question
There are as many atoms in 'X' g of Sulfur as there are in 3 g of carbon. What exactly is 'X'?
- 8
- 16
- 32
- 24
Hint:
Equal number of moles of any element has equal number of atoms.
The correct answer is: 8
Atomic mass of Sulphur is 32 g.
Atomic mass of Carbon is 12 g, 3 g of C is equal to 0.25 mole of C.
Therefore, 0.25 mole of Sulphur is 8 g.
We know, equal number of moles of any element has equal number of atoms.
There are as many atoms in 8 g of Sulfur as there are in 3 g of carbon.
