Answer:
number of particles in 24 grams of carbon-12 = 1.2044 × 10²⁴
Step-by-step explanation:
The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12.
1 mol contains 6.022×10²³ elementary entities of the substance.
Number of moles = Mass / Molar mass
Mass mentioned in the question = 24g
Molar mass of carbon = 12g/mol
Number of moles = 24 /12 = 2 mol
If 1 mol contains 6.022×10²³ elementary entities,
2 mol contains ( 2 * 6.022 × 10²³) = 12.044 × 10²³ number of particles
number of particles in 24 grams of carbon-12 = 1.2044 × 10²⁴
