80g of SO3 contains Na molecules
Weight of 20 molecules of SO3 = (20 * 80)/(Na) grams
Number of oxygen molecules = (Weight of oxygen/Gram Molecular weight of oxygen) * Avagadro number
= ((20 * 80)/(Na * 32)) * Na
= 50
Number of molecules of oxygen is 50
Weight of 20 molecules of SO3 = (20 * 80)/(Na) grams
Number of oxygen molecules = (Weight of oxygen/Gram Molecular weight of oxygen) * Avagadro number
= ((20 * 80)/(Na * 32)) * Na
= 50
Number of molecules of oxygen is 50

Heya
Here goes your answer
Weight of one SO3 molecule=32+3(16)
=32+48
=80
Weight of 20 molecules of SO3=20×80
=1600u
Weight of each molecule of oxygen=2×16=32u
No of oxygen molecules that make up to the weight of 20 molecules of SO3 are = 1600/32
=50
◆50 molecules of oxygen
