Question

calculate the concentration of the final solution, in mol/l. 8.00 x 10^-5 mol was diluted to 500 ml.

Explanation:

Step1: Convert volume to liters

The volume of the final solution is $V = 500\ mL=0.5\ L$.

Step2: Use molarity formula

Molarity $M=\frac{n}{V}$, where $n = 8.00\times10^{- 5}\ mol$ and $V = 0.5\ L$. So $M=\frac{8.00\times10^{-5}\ mol}{0.5\ L}$.

Step3: Calculate molarity

$M = 1.60\times10^{-4}\ mol/L$.

Answer:

$1.60\times10^{-4}$
