For SO₂ in H₂SO₄ :
MW SO₂ = 32 + 2.16=64 g/mol
MW H₂SO₄ =2.1+32+4.16=98 g/mol
The percent of SO₂ :

Isotopes are the atoms of the same element with same atomic number but different mass number isotopes of same element have same chemical properties due to same number of electrons atomic number of an atom is the number of electrons protons in it and mass number is the sum of protons
