Question

12 g of Carbon contains equal number of atoms as

Answer 1

Answer:

one mole of carbon= gram molecular mass of carbon= 12 gram.

one gram of carbon contains× atom and 1 gram=1/2 mole.

therefore 1/12 mole of carbon has X atoms.

equal number of moles of all the elements contains equal atoms, so 1/12 mole of magnesium also contains X atoms.

Explanation:

it is defined as the amount of a substance that contains as many particles are there atoms in 12 gram of pure carbon-12.so one mole contains 6.022 x 10^23 elementary entities of the substance.
