Number of grams of bromine that will completely react with 5.0g5 . 0g of pent-11-ene is____×10−2g\times {10}^{- 2}g. (Atomic mass of Br=80g/molBr = 80g / mol) [Nearest integer]

Correct answer

0

Step-by-step solution


moles of Br2=\mathrm{Br}_2= moles of C5H10\mathrm{C}_5 \mathrm{H}_{10}
⇒w/160=5/70\Rightarrow \mathrm{w} / 160=5 / 70
⇒w=5×160/70 g\Rightarrow \mathrm{w}=5 \times 160 / 70 \mathrm{~g}
=11.428 g=11.428 \mathrm{~g}
=1142.8×10−2 g≈1143×10−2 g=1142.8 \times 10^{-2} \mathrm{~g} \approx 1143 \times 10^{-2} \mathrm{~g}
