QJEEM22Ch4511: JEE Main 2022 Chemistry - Class 11 JEEM22Ch4511 Solution: Number of grams of bromine that will completely react with 5.0…

Molar mass of C₅H₁₀ = 12 $\times$ 5 + 10 = 70 gm

Given mass of C₅H₁₀ = 5 gm

$\therefore$ Moles of C₅H₁₀ = ${5 \over {70}}$

From reaction,

1 mole of C₅H₁₀ reacts with 1 mole of Br₂

$\therefore$ ${5 \over {70}}$ moles of C₅H₁₀ reacts with ${5 \over {70}}$ moles of Br₂

$\therefore$ Reacted Br₂ = ${5 \over {70}}$ $\times$ 160 gm

= 11.428 gm

= 1142.8 $\times$ 10 ^{$-$ 2} gm

$\simeq$ 1143 $\times$ 10 ^{$-$ 2} gm
