A beaker contains 199 mL of NaOH with a concentration of .100 mol/L. Calculate the number of moles of NaOH

moles = M x L = 0.100 x 0.199 =

To calculate the number of moles of NaOH in the beaker, you can use the equation:

moles = concentration (mol/L) × volume (L)

Given:
Concentration of NaOH = 0.100 mol/L
Volume of NaOH = 199 mL

First, convert the volume from milliliters (mL) to liters (L):
199 mL ÷ 1000 = 0.199 L

Now, substitute the values into the equation:
moles = 0.100 mol/L × 0.199 L

Calculate:
moles = 0.0199 mol

Therefore, the number of moles of NaOH in the beaker is 0.0199 mol.
