Answer : The concentration of the is, 0.115 M
Explanation :
Using dilution law,
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of
= 0.125 M
= concentration of KOH = ?
= volume of
= 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the .
Therefore, the concentration of the is, 0.115 M
Answer:
Two conversion factors:
Explanation:
You can create two possible <em>conversion factors</em>, one to convert from mL to L, and one to convert from L to mL
<u />
<u>a) From mL to L</u>
To convert mL to L you need to multiply by a conversion factor that has mL on the denominator and L in the numerator.
Your starting point is:
Then, divide both sides by 1,000mL (this will be on the denominator of the fraction);
<u>b) From L to mL</u>
Divide both sides by 1 L:
