Answer 2

Explanation:

$ANSWER</p><p></p><p>(a) Ethyne (C2H2) = 2×Mass of C atom+2×Mass of H atom=2×12+2×1=24+2=26 g/mol</p><p></p><p></p><p>(b) Sulphur dioxide (S8)=8×Mass of sulphur atom=8×32=256 g/mol</p><p></p><p></p><p>(c) P4=4×Mass of P atom=4×31=124 g/mol</p><p></p><p></p><p>(d) HCl=1×Mass of H atom+1×Mass of Cl atom=1+35.5=36.5 g/mol</p><p></p><p></p><p>(e) HNO3=1×Mass of H atom+1×Mass of N atom+3×Mass of O atom</p><p></p><p>=1×1+1×14+3×16=63 g/mol</p><p></p><p>$
