<u>Answer:</u>
(a): The balloon will contain number of molecules now.
(b): The gas law associated with this is Avogadro's law.
<u>Explanation:</u>
Avogadro's law states that the volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature
Mathematically,
(At constant pressure and temperature)
OR
.....(1)
where,
= Initial volume and number of moles
= Final volume and number of moles
We are given:
Putting values in equation 1, we get:
(a):
If number of moles of gas contains X number of molecules
So, number of moles of gas will contain = number of molecules
Hence, the balloon will contain number of molecules now.
(b): The law used is Avogadro's law.
Answer:
The recovery of pure caffeine is 67.3% of the original, crude sample.
Explanation:
Step 1: Data given
Mass of pure caffeine = 1.69 grams
Original mass of sample = 2.51 grams
Step 2: What is the percent recovery of pure caffeine from crude?
Percentage = (mass of recovery / original mass) *100%
Percentage = (1.69 grams/2.51 grams) *100%
Percentage = 67.3 %
The recovery of pure caffeine is 67.3% of the original, crude sample.
Answer:
82 gallons
Explanation:
There are 3.785 liters in one gallon. In order to get the amount of gallons, divide the amount of liters by 3.785.
310 L ÷ 3.785 L/gal = 81.89 gallons ≈ 82 gallons
