Reaction

2H₂ + O₂ ⇒ 2H₂O

mole H₂ = 17.14 : 2 g/mole = 8.57

mole O₂ = 1.14 L : 32 g/mole = 0.0356

O₂ as a limiting reactant (smaller mol ratio)

mole H₂O = 2/1 x mole O₂ = 2/1 x 0.0356 = 0.0712

Helium gas diffuses 4 times as fast as an unknown gas. What is relative molecular mass of the gas

Inessa05 [86]

The relative molecular mass of the gas : 64 g/mol

<h3>Further explanation</h3>

Given

Helium rate = 4x an unknown gas

Required

The relative molecular mass of the gas

Solution

Graham's Law

$\tt \dfrac{r_1}{r_2}=\sqrt{\dfrac{M_2}{M_1} }$

r₁=4 x r₂

r₁ = Helium rate

r₂ = unknown gas rate

M₁= relative molecular mass of Helium = 4 g/mol

M₂ = relative molecular mass of the gas

Input the value :

$\tt \dfrac{4r_2}{r_2}=\sqrt{\dfrac{M_2}{4} }\\\\16=\dfrac{M_2}{4}\\\\M_2=64~g/mol$
