Answer:
<h3>The answer is 0.91 %</h3>Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 198.2 mL
error = 200 - 198.2 = 1.8
So we have
We have the final answer as
<h3>0.91 %</h3>Hope this helps you
The molarity of the NaOH solution is 0.036 M
First, we will write the balanced chemical equation for the reaction
The balanced equation of reaction between HCl and NaOH is
HCl + NaOH → NaCl + H₂O
In the balanced chemical equation above,
It means 1 mole of HCl is required to completely neutralize 1 mole of NaOH
To determine the molarity of the NaOH solution,
We will determine the number of moles of HCl that reacted
From the question,
Volume of HCl = 25.0 mL = 0.025 L
Concentration of HCl = 0.050 M
From the formula
Number of moles = Concentration × Volume
Then,
Number of moles of HCl = 0.050 × 0.025
Number of moles of HCl = 0.00125 moles
This means 0.00125 moles of HCl reacted with 0.00125 moles of NaOH
Now, to determine the molarity (that is concentration) of NaOH,
Number of moles of NaOH = 0.00125 moles
Volume of NaOH = 34.5 mL = 0.0345 L
From the formula
Number of moles = Concentration × Volume
Then,
∴ Concentration of NaOH = 0.03623 M
Concentration of NaOH = 0.036 M
Hence, the molarity of the NaOH solution is 0.036 M
