Which of the following gases effuses the fastest at a given temperature?
Sholpan [36]

Answer: -

H₂ will diffuse the fastest.

Explanation: -

According to Graham's Law of Diffusion

The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.

Molar mass of Ne = 20 g / mol

Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol

Molar mass of Ar = 40g / mol

Molar mass of H₂ = 1 x 2 = 2 g / mol

Thus H₂ will diffuse the fastest.

To dilute a HCl solution from 0.400 M to 0.100 M the final volume must be
sp2606 [1]

<u>Answer:</u>

<em>The final volume must be 400 mL.</em>

<em></em>

<u>Explanation:</u>

Let us assume the Initial volume as 100ml

Using dilution factor formula  

\\$M_{1} \times V_{1}=M_{2} \times V_{2}$\\\\$0.400 M \times 100 m l=0.100 M \times V_{2}$

So,

$V_{2}=\frac{0.400 M \times 100 m l}{0.100 M}=400 m l$

Thus, the final volume must be 400 mL.
