Answer 1

0.5 mol Na₂CO₃ represents that there are 3.011*10²³ molecules of Na₂CO₃

i.e 0.5 mol Na₂CO₃  => 0.5 * Molar mass = 0.5 * ((23*2)+(12*1)+(16*3))

                                                                   = 0.5 * 106

                                                                   = 53 gm Na₂CO₃

0.5 M Na₂CO₃ represents that 0.5 mol Na₂CO₃ is dissolved in 1 liter of water

∴ 0.5 mole Na₂CO₃ ==> 53 gm Na₂CO₃

0.5 M Na₂CO₃ ==> 53 gm Na₂CO₃ dissolved in 1 liter water

OFF COURSE THEY ARE DIFFERENT 0.5 moles Na2CO3 means just Na2CO3 ,
BUT
0.5 M (MOLARITY :- NUMBER OF MOLES OF SOLUTE ÷VOLUME OF SOLUTION ) Na2CO3 means NOT ONLY Na2CO3 but it is dissolved in solvent .

SO THESE BOTH ARE KINDA DIFFERENT FROM EACH OTHER
