Molecular formula – H2O2

Question

Deduce the molecular masses of those compounds:

Atomic masses – H(l), 0(16), N(14), C(12), K(39), S(32) Ca(40), Na(23), Cl(35.5), Mg(24), Al(27)

Molecular formula – H₂O₂

Answer 1

Molecular mass of H₂O₂ (M) 

= (Atomic mass of H) x 2 + (Atomic mass of O) x 2 

= (1 x 2) + (16 x 2) 

= 2 + 32 

= 34 

∴ Molecular mass of H₂O₂ (M) = 34
