What is the number of oxygen atoms in 32g of the gas? (O = 16, L = 6.0 X 10\(^{23}\) mol\(^{-1}\))
A
3.2 X 10 23
B
6.0 X 1023
C
1.2 X 1024
D
1.6 X 1024
E
2.0 X 1024
Verified Correct Answer: B.
Chemical Principles & Mechanism
Oxygen is Diatomic
: 1 mole of oxygen contains 2 ATOMS
→ 2 X 16g = 32g
32g of the gas = 6.0 X 10\(^{23}\) mol\(^{-1}\)
