State whether the following statements are true or false:
$(i)$ $^\circ F = \frac{9}{5} (^circ C) + 32$
$(ii)$ In $1808$,Dalton published the law of chemical combination in the journal "New System of Chemical Philosophy".
$(iii)$ If the molar mass of a dibasic acid is $100$,its equivalent mass is $200$.

(N/A) $(i)$ True: This is the standard conversion formula between Fahrenheit and Celsius scales.
$(ii)$ False: John Dalton published his work in the book titled "$A$ New System of Chemical Philosophy" in $1808$,which laid the foundation for modern atomic theory.
$(iii)$ False: For a dibasic acid,the equivalent mass is calculated as $\frac{\text{Molar Mass}}{\text{Basicity}} = \frac{100}{2} = 50$,not $200$.
