iska Uttar kya hoga

Following is your answer-
(a) O₂ - 32  Because the atomic mass of oxygen is 16, so two oxygen atoms make their mass as 32
(b) CH₄ -  Atomic mass of 1 Carbon = 12
                The atomic mass of 4 Hydrogen = 4
                Molecular mass of CH₄ = 12 +4 = 16
 (c) HNO_3 -  The molar mass of nitric acid is 63.01 g/mol.   
(d) H_{2o  -}  Atomic mass of 2-Hydrogens = 2
                Atomic mass of 1- Oxygen = 16
                Molecular mass of H₂O = 2 + 16 = 18
