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.

Step 1

**Given: **

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 :**

M1V1=M2V2

Substitute and simplify the known values,

M1 X 8 = 0.199 X 8.17

M1 ...
