Question

Calculate the number of atoms in each of the following :


(iii) 0.2 mole of CH4​

Answer 1

Answer:

no. of mole=no. of atom/avagadro no.

0.2 =no. of atom/6.022*10^22

no. of atom=1.2044*10^22

Answer 2

Answer:

We know that 1 mole of sodium contains Avogadro number of atoms. - But we have to find the number of atoms in 0.2 mole of sodium. - Therefore 0.2 moles of sodium (Na) contains 12.046×1023atoms in it.
