Question:
Each liter of air has a mass of 1.80 grams. How many liters of air are contained in 2.5 x103) kg of air?
Answer:
11.48106 L
Answer:
Spontaneous and random. Decay is called spontaneous because the occur on their own and are unaffected by external factors like temperature, pressure, and many more. Decay is called random because we cannot determine the rate at which it decays but can only determine the probability of the decay.Oct 21, 2015
Explanation:
Solution :
From Fick's law:
Mass balance: Exits = Accumulation
From the last step, area cancels out and thus leaves :
So now we can substitute the by the Fick's law
Substituting the values we get
This is in the assumption that these are the only 2 isotopes. This means that:
abundance of Li-6 = X
abundance of Li-7 = 1-X
Hence from your equations
6.9409 = (X * 6.015121amu) + ((1-X) * <span>7.016003amu</span>)
Solve for X = 0.075 or 7.50%
