what is the original concentration of a solution in which 83.5 ml of the concentrated solution is diluted to 500. ml of 0.5 m solution?\n? m solution

Answer

Answer:

$3.00\ M$

Explanation:

Step1: Identify dilution formula

$M_1V_1 = M_2V_2$

Step2: Define variables

$M_1$ is unknown, $V_1=83.5\ mL$, $M_2 = 0.5\ M$, $V_2 = 500\ mL$

Step3: Rearrange formula for $M_1$

$M_1=\frac{M_2V_2}{V_1}$

Step4: Substitute values

$M_1=\frac{0.5\ M\times500\ mL}{83.5\ mL}$

Step5: Calculate result

$M_1 = 3.00\ M$
