Best answer
ग्राह्म के विसरण नियम से,
`(r_(H_(2)))/(r_(O_(2)))=(V_(H_(2))//t_(H_(2)))/(V_(O_(2))//t_(O_(2)))=sqrt((M_(O_(2)))/(M_(H_(2))))`
(प्रश्नानुसार `V_(H_(2)) = 25` मिली, `t_(H_(2)) = 50` सेकण्ड, `M_(H_(2)) = 2`,
`V_(O_(2)) = 20` मिली, `t_(O_(2)) = ?, " "M_(O_(2)) = 32`)
`(25//50)/(20//t_(O_(2)))=sqrt([(32)/(2)])`
`(1)/(2) xx (t_(O_(2)))/(20) = 4 rArr " "t_(O_(2)) = 160` सेकण्ड
