(a) Ethyne (

C_{2} H_{2}

) = 2xmass of atom +2xmass of H Atom =2x12+2x1=26 g/mol
(b) Sulphur dioxide(

S_{8}

)= 8xmass of sulphur atom =8x32=256g/mol
(c)

P_{4}

= 4xMass of P atom =4x31 =124g/mol
(d) HCL = 1x Mass of H atom+1xmass of Cl atom= 1+35.5 =36.5g/mol
(e)

H N O_{3}

=1x mass of H atom +1x mass of N atom +3x Mass of O atom =1x1+1x14+3x16 = 63g/mol
