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= 560+10=570 ∴w160=570 ∴w=5*16070=807g =1142.8*10−2≈1143*10−2g

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

$∴ \frac{w}{160} = \frac{5}{70}$

$∴ w = \frac{5 * 160}{70} = \frac{80}{7} g$

$= 1142.8 * 1 0^{- 2} \approx 1143 * 1 0^{- 2} g$
