Answer:
2 mL of Solution A must be added to Solution B to give a buffer that is equimolar.
Explanation:
Given the data in the question;
First we determine the number of sodium acetate;
⇒ molarity × volume ( L )
⇒ 0.16 × 2.0 mL
⇒ 0.16 × 0.002 L
⇒ 0.00032
Now, Molarity of sodium acetate = moles / Volume(L)
⇒ ( 0.00032 / 50 ) × 1000
⇒ 0.0064
Since number of moles of acetic acid that should be added tp make equimolar solution is 0.00032
and Molarity of acetic acid is 0.16 molL⁻¹
Let X represent the volume that should be added.
so;
Molarity = Moles / Volume (L)
we substitute
0.16 = (0.00032 / X) × 1000
0.16 = 32 / X
X = 0.32 / 0.16
X = 2 mL
Therefore, 2 mL of Solution A must be added to Solution B to give a buffer that is equimolar.
The equation for ideal gas law is written as PV = nRT.
<h3>What is Ideal gas law?</h3>
Ideal gas law states that, the volume of a given amount of gas is directly proportional to the number on moles of gas, directly proportional to the temperature and inversely proportional to the pressure.
PV = nRT
where;
- P is pressure of the gas
- V is volume of the gas
- n is number of moles
- R is ideal gas constant
- T is temperature
Thus, the equation for ideal gas law is written as PV = nRT.

apply quantum theory to, especially form into quanta, in particular restrict the number of possible values of (a quantity) or states of (a system) so that certain variables can assume only certain discrete magnitudes.
Based on the freezing point depression value of HCl in benzene, HCl does not act as an electrolyte in benzene.
<h3>What is the effect of solute on the freezing point of a solvent?</h3>
The freezing point of a solvent such as water is lowered by the solute which ionizes in it.
The freezing point of a solution depends on the number of particles in the solution.
The formula for freezing point depression is given below:
ΔTf = i * Kf * m
HCl remains as molecules and does not ionize in a solution of Benzene. This is because benzene is a nonpolar solvent.
Therefore, the equation for the dissolution of HCl in benzene is given below:
HCl (g) → HCl (in benzene solution)
1 mol of HCl gas gives 1 mol of HCl molecules in solution.
Therefore, HCl remains a molecule and does not act as an electrolyte in benzene.
