naoh?

To find the amount of NaOH in 2.5 mL of a 0.05 M NaOH solution, we can use the formula:

Amount of NaOH (in moles) = Volume (in liters) x Concentration (in Molarity)

First, convert the given volume from milliliters to liters by dividing by 1000:
2.5 mL ÷ 1000 = 0.0025 L

Then, substitute the values into the formula:
Amount of NaOH (in moles) = 0.0025 L x 0.05 M = 0.000125 moles

Therefore, there is approximately 0.000125 moles of NaOH in 2.5 mL of a 0.05 M NaOH solution.
