<h2>Hello!</h2>
The answer is:
First, we need to calculate the molecular weight of the acetone (CH3COCH3)
So,
Then,
Second, we need to calculate the mass of the acetone in the bottle
We need to remember that
So,
Third, we need to calculate the number of moles:
Fourth, we need to calculate the number of atoms:
Remember,
Therefore,
Have a nice day!
Answer:
See explanation.
Explanation:
Hello
(a) In this case, one uses the following formulas, which allow to compute the mass fraction of each component:
(b) For the mole fractions, it is necessary to find all the components' moles by using their molar mass as shown below:
Now, the mole fractions:
(c) Finally the average molar mass is computed considering the molar fractions and each component's molar mass:
And the gas constant:
