Question

Raunak took 5 moles of carbon atoms in a container and rani also took 5 moles of sodium atoms in another container of same weight.Whose container is heavier?Whose container has more number of atoms?

Answer 1

mol of a substance =atomic Wt.expressed in gms.

1mol.of C=12g &1 mol.of Na=23g

5mol.of C=60 g &5 mol of Na=115g

hence Rani container is heavier

one mole of any substance always has 6.023×10^23 atoms so 5 moles=30×10^23 atoms of both C and Na same no.of atoms
