2 C8H18 + 25 O2 = 16 CO2 + 18 H2<span>O
Above is properly balanced but as you want 1 mole. divide everything by 2
</span>C8H18 + 12.5O2 = 8CO2 + 9H2<span>O</span>
For this problem, we use Graham's Effusion Law to find out the rate of effusion of chlorine gas. The formula is as follows:
R₁/R₂ = √(M₂/M₁)
Let 1 be N₂ while 2 be Cl₂
255/R₂ = √(28/70.8)
Solving for R₂,
R₂ = 405.5 s
<em>Thus, it would take 405.5 s to effuse chlorine gas.</em>
