सही उत्तर 0.25 है

अवधारणा:

मोल:

  • मोल पदार्थ की मात्रा के लिए माप की एक इकाई है।
  • किसी भी पदार्थ के एक मोल में ठीक \(6.022 \times 10^{23}\) इकाइयाँ होती हैं (इस संख्या को आवोगाद्रो संख्या \(N_A\) के रूप में जाना जाता है।
  • मोल की गणना करने का सूत्र: \(n = \frac{N}{N_A}\)

गणना:

दिया गया है,

\( CO_2 \) के अणुओं की संख्या \( N = 1.506 \times 10^{23}\)

आवोगाद्रो संख्या, \(N_A = 6.022 \times 10^{23} \, \text{molecules/mol}\)

\(CO_2\) के मोलों की संख्या,

\(n = \frac{N}{N_A}\)

\( n = \frac{1.506 \times 10^{23}}{6.022 \times 10^{23}}\)

\(n \approx 0.25 \ moles\)

\( CO_2 \) के मोलों की संख्या 0.25 है।
