Question

Find the number of atoms present in \(11.2\ \text{L}\) of nitrogen gas at STP.

• A. \(3.01 \times 10^{23}\)
• B. \(6.02 \times 10^{23}\)
• C. \(12.04 \times 10^{23}\)
• D. \(1.204 \times 10^{23}\)

Hint:

Useful STP facts:
• \(22.4\ \text{L}\) gas at STP \(= 1\) mole
• \(1\) mole \(= 6.02 \times 10^{23}\) molecules
• For diatomic gases like \(H_2, N_2, O_2, Cl_2\): \[ \text{Atoms} = 2 \times \text{Number of molecules} \]

Answer 1

The Correct Option is B
