Q3.) acidic
q4.)that the solution is acidic
q5.)that the solution is alkaline
The number of mole of NaOH that was used, given that 3.85 mL of 10.0 M NaOH is used in the reaction is 0.0385 mole
<h3>How do I determine the number of mole of NaOH?</h3>
We know that molarity is related to number of mole and volume according to the following formula:
Molarity = number of mole / Volume
With the above formula, we can determine the number of mole of NaOH. Details below
The following data were obtained from the question:
- Volume = 3.85 mL = 3.85 / 1000 = 0.00385 L
- Molarity = 10.0 M
- Number of mole of NaOH =?
Molarity = number of mole / Volume
Cross multiply
Number of mole = molarity × volume
Number of mole of NaOH = 10 × 0.00385
Number of mole of NaOH = 0.0385 mole
Thus, the number of mole of NaOH is 0.0385 mole
