This problem could be solved through the Graham’s law of
effusion (also known as law of diffusion). This law states that the ratio of
the effusion rate of the first gas and effusion rate of the second gas is
equivalent to the square root of the ratio of its molar mass. Thus the answer
would be 0.1098.
The answer would be B. Liquid
When the crystals of potassium permanganate are preserved in water, the purple-coloured crystals of potassium permanganate break further into smaller particles that populate the distance between the molecules of water imparting a purple colour to the water. This is an example of diffusion.
<h3>What are the two conclusions given out in the method of diffusion?</h3>
Diffusion is the process of movement of solvent from higher concentration to lower concentration through a semipermeable membrane. So, we can form the decision that it cannot occur through a thick membrane from which small molecules cannot pass through.
<h3>What is difference between osmosis and diffusion?</h3>
Osmosis is the direction of solvent particles from a solution that is diluted to a more concentrated one. In contrast, diffusion is the movement of particles from a higher concentration region to a part of lower concentration.

The question says only to convert the Zn(OH)₂ into moles. But the given answer has many errors such as formula, mass and moles.
<span>The corrected answer is as follows.
</span>Moles (mol) = mass (g) / molar mass (g/mol)
<span>
</span><span>Mass of Zn(OH)₂</span><span> = 0.45 g
Molar mass of Zn(OH)₂ = </span><span>99.424 g/mol
</span>Hence, moles of Zn(OH)₂ = 0.45 g / 99.424 g/mol
<span> = 4.526 x 10⁻³ mol

I don't care but one another time and I have any questions about this email
