For a liter of a buffer that is 1. 5 m in acetic acid and 0. 70 m in sodium acetate, and with a result in a buffer pH of 4.01, the moles of HCl required is mathematically given as x=0.313mol
<h3>What is the result in a buffer ph of 4. 01?</h3>
Generally, the equation for the pH is mathematically given as
pH=pKa+logsalt/acid
Generally, the equation for the Chemical Reaction is mathematically given as
HCl+CH3CooNa---->NaCl+CH3OOH
Therefore
4.01=4.74+log\frac{0.8-x}{1.3+x}
-0.52=log\frac{0.8-x}{1.3+x}
x=0.313mol
In conclusion, The moles of HCl required is
x=0.313mol

Answer:
1.33 M
Explanation:
We'll begin by writing out the data obtained from the question. This includes the following:
Volume of the stock solution (V1) = 0.5L
Molarity of the stock solution (M1) = 4M
Volume of diluted solution (V2) = 1.5L
Molarity of the diluted solution (M2) =.?
With the application of the dilution formula, the molarity of the diluted solution can be obtained as follow:
M1V1 = M2V2
4 x 0.5 = M2 x 1.5
Divide both side by 1.5
M2 = (4 x 0.5) / 1.5
M2 = 1.33 M
Therefore the molarity of the diluted solution is 1.33 M
