Deduce the molecular masses of those compounds:Atomic masses – H(l),

1.	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 – HNO3
Answer» Molecular mass of HNO₃ (M) = (Atomic mass of H) x 1 + (Atomic mass of N) x 1 + (Atomic mass of O) x 3 = (1 x 1)+ (14 x 1)+ (16 × 3) = 1 + 14 + 48 = 63 Molecular mass of HNO₃ (M) = 63

Answer»

Molecular mass of HNO₃ (M)

= (Atomic mass of H) x 1 + (Atomic mass of N) x 1 + (Atomic mass of O) x 3

= (1 x 1)+ (14 x 1)+ (16 × 3)

= 1 + 14 + 48

= 63

Molecular mass of HNO₃ (M) = 63
