Number of grams of bromine that will completely react with 5.0g of pent-1-ene is_____________×10^-2g. (Atomic mass of Br = 80 g/mol) (Nearest Integer)

Moles of Br₂= moles of C₅H₁₀= $\frac{5}{60+10}=\frac{5}{70}$

$\therefore \frac{w}{160}=\frac{5}{70}$

$\therefore w=\frac{5\times 160}{70}=\frac{80}{7}g$

$=1142.8\times 10^{-2}\approx 1143\times 10^{-2}g$
