Question

a certain amount of unknown gas occupies 900 ml at 27 degree Celsius and 1.2 ATM was the same amount of hydrogen occupies 1.4 litre at 45 degree Celsius and 1.2 ATM calculate the ratio of diffusion of hydrogen and the gas under identical condition

Answer 1

$\mathfrak{\huge{\blue {\underline{\underline{AnswEr :}}}}}$

given constant pressure, and constant amount of gas.

V ∝ T

i.e.

V = kT

and under DIFFERENT conditions of temperature, we solve for k

$\large{\frac{V1}{T1} = \frac{V2}{T2}}$ pressure and amount of gas are ASSUMED to be constant and temperature is specified on the absolute scale.

We solves for

$\large{V2 = \frac{V1}{T1}\times T2 }$

$\large{V2 =\frac{900ml}{300k}\times392K}$

⚘ We gots approx 1.2 ⋅L
