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 – H2SO4
Answer» Molecular mass of H₂SO₄ (M) = (Atomic mass of H) x 2 + (Atomic mass of S) x 1 + (Atomic mass of O) x 4 = (1 x 2) + (32 x1) + (16×4) = 2 + 32 + 64 = 98 Molecular mass of H₂SO₄ (M) = 98

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 – H2SO4

Answer»

Molecular mass of H₂SO₄ (M)

= (Atomic mass of H) x 2 + (Atomic mass of S) x 1 + (Atomic mass of O) x 4

= (1 x 2) + (32 x1) + (16×4)

= 2 + 32 + 64

= 98

Molecular mass of H₂SO₄ (M) = 98
