What is the number of oxygen atoms in 32g of the gas? (O = 16, L = 6.0 X 10\(^{23}\) mol\(^{-1}\))
- 3.2 X 10 23
-
6.0 X 1023
- 1.2 X 1024
- 1.6 X 1024
- 2.0 X 1024
The correct answer is: B
Explanation
Oxygen is Diatomic
: 1 mole of oxygen contains 2 ATOMS
→ 2 X 16g = 32g
32g of the gas = 6.0 X 10\(^{23}\) mol\(^{-1}\)
