The molar mass of a gas that travels with an effusion time that is 1.94 times longer than that of HCl (g) is 137 g/mol
<h3>What is the relationship between the molar mass of a gas and the effusion time of a gas?</h3>
The relationship between the molar mass of a gas and the effusion time of a gas is given by the equation below:
T₁/T₂ = √M₁/√M₂
where;
T₁ is the time of effusion of HCl
T₂ is the time of effusion of the gas
M₂ is the molar mass of the gas
M₁ is the molar mass of HCl = 36.5 g/mol
T₂ = 1.94T₁
1 / 1.94 = √36.5 /√M₂
M₂ = 137 g.mol
