Answer:
EAST is the answer
Explanation:
For the moment, let us just think about one motion - - Earth's spin (or rotation) on its axis. Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky.
To answer this question, you need to know <span>Graham's Law of Effusion/Diffusion formula. In this formula, the rate of diffusion/effusion would be influenced by the mass. As the molecule has bigger mass, the rate should be slower because it will be harder to pass the membrane. The calculation should be:</span>
<span>Rate 1 / Rate 2 = √[M2/M1]
</span>4.11/1= √[M2/2]
M2=33.78 g/mol
Answer:

<u>Answer:</u> The correct answer is option A.
<u>Explanation:</u>
To calculate the volume of an object, we use the formula:

We are given:
Density of an object = 
Mass of an object = 8.2 grams
Volume of an object = ?
Putting values in above equation, we get:


Hence, the correct answer is Option A.
