Question

Standard Solution and Dilution Dry Post-Lab1.) If you add water to 100 mL of a 0.150M NaOH solution until the final volume is 150 mL, what will be the concentration of the solution be?Round your answer to three significant digits.

Answer 1

To solve the question, you need to use the following formula

$C_1V_1=C_2V_2$

where V volumes and C concentrations

Data

C₁=100 mL

V₁= 0.150 M

C₂=

V₂= 150 mL

$C_2=\frac{C_1V_1}{V_2}=\frac{150\text{ M }0.100\text{ mL }}{150\text{ mL}}=0.10\text{ M NaOH}$
