If you have 2.4L of SO2 gas (at STP) how many moles of sulfur dioxide do you have?
Andru [333]

Answer:

0.107 mole of SO2.

Explanation:

1 mole of a gas occupy 22.4 L at standard temperature and pressure (STP).

With the above information, we can simply calculate the number of mole of SO2 that will occupy 2.4 L at STP.

This can be obtained as follow:

22.4 L contains 1 mole of SO2.

Therefore, 2.4 L will contain = 2.4/22.4 = 0.107 mole of SO2.

Therefore, 0.107 mole of SO2 is present in 2.4 L at STP.

g On the basis of their respective pKa values, determine which is the stronger acid, acetic acid (pKa 5 4.7) or benzoic acid (ma
ozzi

Answer:

Benzoic acid is the stronger acid

Explanation:

Weak acids do not dissociate completely in the solution. They exists in equilibrium with their respective ions in the solution.

The extent of dissociation of the acid furnising hydrogen ions can be determined by using dissociation constant of acid (K_a).

Thus for a weak acid, HA

HA \rightleftharpoons A^- + H^+

The K_a is:

K_a= \frac{[A^-][H^+]}{[HA]}

The more the K_a, the more the acid dissociates, the more the stronger is the acid.

Also,

pK_a is defined as the negative logarithm of K_a.

So, more the pK_a, less is the K_a and vice versa

All can be summed up as:

The less the value of pK_a, the more the  K_a is and the more the acid dissociates and the more the stronger is the acid.

Given,

pK_a of acetic acid = 54.7

pK_a of benzoic acid = 54.2

pK_a of benzoic acid < pK_a of acetic acid

So, benzoic acid is the stronger acid.
