First of all convert 11 gm seo2 into nu of mole, then multiply nu of mole into
6.023 × 10^23
Molecular mass of seo2 = 79+ 32= 111
Means 1 mole of seo2 has 111 gm
Then 11 gm seo2 has 11/111 mole = 0.09
Then nu of molecules in 11 gm seo2 has = 0.09 × 6.023×10^23
= 5.4 ×10^22 molecules
6.023 × 10^23
Molecular mass of seo2 = 79+ 32= 111
Means 1 mole of seo2 has 111 gm
Then 11 gm seo2 has 11/111 mole = 0.09
Then nu of molecules in 11 gm seo2 has = 0.09 × 6.023×10^23
= 5.4 ×10^22 molecules
