The reaction shown in the question is a Wurtz-Fittig reaction. This reaction involves the reaction of an alkyl halide (R-X) with sodium in dry ether, leading to the formation of an alkane (X) or an alkylated product (Y). It is a combination of the Wurtz reaction (for alkyl halide formation) and the Fittig reaction (for aryl halide formation).
The Wurtz-Fittig reaction is a combination of both reactions and is used to form aryl and alkyl products.
Consider the following sequence of reactions : 
Molar mass of the product formed (A) is ______ g mol\(^{-1}\).
Predict the major product $ P $ in the following sequence of reactions:
(i) HBr, benzoyl peroxide
(ii) KCN
(iii) Na(Hg), $C_{2}H_{5}OH$
