Rate of effusion "=" "Amount of gas \\over time"
Combine with Grahams law;
"Rate of effusion of hydrogen\\over Rate of effusion of Oxygen" "=" "\\sqrt MO \\over \\sqrt MH"
To get
"{Amount of H transferred \\over time of H} \\over{Amount of O transfared\\over time of O}" "=" "\\sqrt MO \\over \\sqrt MH"
"\\therefore" "Time of H\\over Time of 0" "=" "\\sqrt MO\\over \\sqrt MH" "=" "\\sqrt MO\\over \\sqrt MH"
"Time of O\\over 4s" "=" "\\sqrt 32g\/mol \\over 2mol\/L" "=" "\\sqrt 16 \\over \\sqrt 1"
"Time of O \\over 4s" "=" "4\\over 1"
"=4*4=16"
Oxygen takes "16" seconds to travel through the same distance.
