Question

how many atoms are there in exactly 12kg of carbon -12 element?​

Answer 1

Answer:

Explanation:

There are $6.022^{23}$ atoms in 12 grams carbon

12Kg = 12 x 1000g

        = 12000g

therefore 12 Kg of carbon has  $6.022^{23}$ x ( 1 x $10^{3}$ )  atoms

which is equal to $7.022^{26}$

therefore 12Kg of carbon has $7.022^{26}$ atoms
