Answer:
The molar mass of the unknown gas is 154.4 g/mol
Explanation:
Step 1: Data given
It takes 986 seconds for an unknown gas to effuse
It takes 811 seconds for chlorotrifluoromethane (CClF3) gas to effuse
Molar mass of chlorotrifluoromethane (CClF3) = 104.46 g/mol
Step 2: Calculate the molar mass of the gas
t1/t2/ √(M1/M2)
⇒with t1 = the time needed for the unknown gas to effuse = 986 seconds
⇒with t2 = the time needed for CClF3 to effuse = 811 seconds
⇒with M1 = the molar mass of the unknown gas = TO BE DETERMINED
⇒with M2 = the molar mass of CClF3 = 104.46 g/mol
986/811 = √(M1/104.46)
(986/811)² = M1 / 104.46
M1 = 154.4 g/mol
The molar mass of the unknown gas is 154.4 g/mol
Answer:
I think the correct answer for this is False.
The displacement affect the amount of work done by the fact that more displacement implies more work.
Option B
<u>Explanation:</u>
Work can be defined as the "measure of energy transfer" that occurs when an object is moved over a distance by an external force which is applied in the "direction of the displacement".
Work can be formulated as,

From the above-mentioned formula, we can infer that Work is directly proportional to the displacement of the object.Therefore, more the work is more will be its displacement.
Answer:
C is the answer to the question
Your answer is correct, I do not understand why it would be wrong.
