Which of the following is/are correct about 1 mole electrons? This question has multiple correct options
- A. \( 6.023 \times 10^{23} \) electrons
- B. \( 5.48 \times 10^{-7} \mathrm{kg} \)
- C. 96500 coulomb charge
- D. None of these
Step-by-step solution
All three statements A, B, and C are correct approximations for 1 mole of electrons. A gives the number of electrons equal to Avogadro's number (6.022×10^23, often approximated as 6.023×10^23). B gives the total mass (about 5.48×10^-7 kg). C gives the charge (96500 C, the Faraday constant). Since all are correct, D is incorrect. The single best option is A as it directly defines 1 mole.
