alleryAvogadro's number is:
A3.011 * 10^23
B6.022 * 10^23
C6.022 * 10^-23
D9.11 * 10^31
Answer & Solution
Correct answer: B. 6.022 * 10^23
1. Avogadro's number is the count of particles in one mole.
2. Its accepted value is 6.022 * 10^23.
3. The same constant works for atoms, molecules or ions.
4. So one mole contains 6.022 * 10^23 entities.
