Step-by-step explanation:
Answer:
140.32mL per hour
Step-by-step explanation:
Rate of leakage of nitrogen ballon = 75 mL/h
Rate of leakage of helium ballon = x
Molar mass of nitrogen= Mn = 14
Molar mass of helium = Mh = 4
Effusion formula
Rate of effusion of helium/ Rate of effusion of nitrogen= √(Molar mass of nitrogen/Molar mass of helium)
Rate of effusion of helium = 75mL/h * √(14/4)
= 140.32mL/h
Answer:
Correct choce is (a). 30.
Step-by-step explanation:
Given equation is
.
Now we need to find the value of (fof)(3). Then select correct matching choice from the given choices. Where given choices are:
(a). 30
(a). 33
(a). 6
(a). -6
Now let's find 







Hence correct choce is (a). 30.
My best guess is a 1/225 chance in guess the right combination
