Vedclass · Answer

(A) The chemical reaction is: $CH_3-CH=CH_2 + Br_2 ightarrow CH_3-CH(Br)-CH_2(Br)$ The molar mass of propene $(C_3H_6)$ is $(3 	imes 12) + (6 	imes 1) = 42\, g/mol$. The molar mass of bromine $(Br_2)$ is $2 	imes 80 = 160\, g/mol$. According to the stoichiometry,$1$ mole of propene reacts with $1$ mole of bromine. Thus,$42\, g$ of propene reacts with $160\, g$ of bromine. Therefore,$21\, g$ of propene will react with $\frac{160}{42} 	imes 21 = 80\, g$ of bromine.

How many $g$ of bromine will react with $21\, g$ of $C_3H_6$?
