Calculate the concentration (in M) of the unknown NaOH solution in the first case.


NaOH volume (mL) HCl volume (mL) [HCl] (M)
8.00 8.17 0.1999


Express your answer using three significant figures.

Expert Answer

Step 1


Volume of NaOH = 8.00 mL = V1

Volume of HCl = 8.17 mL = V2

Molarity of HCl = 0.199 = M2

We need to calculate the concentration (in M) of the unknown NaOH  (M1)

Step 2

Formula :


Substitute and simplify the known values,

M1 X 8 = 0.199 X 8.17

M1 ...
