A titration required 23.8ml of a 0.15 M NaOH solution. How many moles of NaOH were in this volume?
moles=molarity*volumeinLiters=.15*.0238= ....
To find the number of moles of NaOH in the given volume, we need to use the formula:
moles = concentration × volume
First, let's convert the given volume to liters since the concentration is given in moles per liter (M):
Volume = 23.8 ml = 23.8/1000 = 0.0238 L
Now, we can calculate the number of moles using the concentration and volume:
moles = 0.15 M × 0.0238 L
moles = 0.00357 mol
Therefore, there were 0.00357 moles of NaOH in the 23.8 ml volume.
