In a volumetric flask of 500,0 mL we put 2,456 g NaOAc. We add 25.0 mL HOAc 1.00 mol/L. We fill with water. Calculate pH.
a |
How many moles of NaOAc are present in the flask? |
![0.0300 mol](../../images/vraagteken.jpg)
|
b |
How many moles of HOAc are present in the flask? |
![0.0250 mol/L](../../images/vraagteken.jpg)
|
c |
What is the concentration of NaOAc in the mixture? |
![0.0600 mol/l](../../images/vraagteken.jpg)
|
d |
What is the concentration of NaOAc in the mixture? |
![0.0500 mol/L](../../images/vraagteken.jpg)
|
e |
