Question

Determine the molecular mass of the following compounds

Answer 1

(a).

(4 × C) + (8 × H)

= (4 × 12) + (8 × 1)

= 48+8

= 56 g

(b).

= (4 × C) + (6 × H)

= (4 × 12) + (6 × 1)

= ( 48+6 )

= 54 g

(c).

= ( 2 × Si ) + ( 4×Cl ) + (2×H)

= (2×28) + (4×35.5) + (2×1)

= 56 + 142 + 2

= 200 g

(d).

= (1×P) + (4×O) + (3×H)

= 31 + 64 + 3

= 98 g
