know that relative atomic mass of 12CX12X2212C is 12 u12 u.

Therefore mass of 1 mol C=12 g1 mol C=12 g

mass of 6.022⋅1023 C atomsmass of 1 C atom=12 g=12 g6.022⋅1023=1.99⋅10−23 g,mass of 6.022⋅1023 C atoms=12 gmass of 1 C atom=12 g6.022⋅1023=1.99⋅10−23 g,

but

1 u⟹Mass of 1 12C atom=1.66⋅10−24 g=1.66⋅12⋅10−24 g=19.92⋅10−24 g=1.992⋅10−23 g
