Mole is defined as the number of atoms found in ____ of carbon-12?
|
|
10 grams
|
|
|
11 grams
|
|
|
12 grams
|
|
|
13 grams

Explanation:
Detailed explanation-1: -The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).
Detailed explanation-2: -1 mole of carbon. Exactly 12 grams of pure carbon-12 powder is known as one mole. The number of atoms of carbon-12 present in this one mole sample is 6.022 136 7 x 1023. This number is known as Avogadro’s number.
Detailed explanation-3: -AMU is defined as one-twelfth the mass of an atom of carbon-12 (12C). 12. C is the most abundant natural carbon isotope, accounting for over 98% of carbon found in nature.
