what is the original concentration of a solution in which 100.0 ml of the concentrated solution is diluted to 250. ml of 2.0 m solution? ? m solution
Answer
Explanation:
Step1: Recall dilution formula
$M_1V_1 = M_2V_2$
Step2: Identify given values
$V_1=100.0\ mL$, $V_2 = 250\ mL$, $M_2=2.0\ M$
Step3: Solve for $M_1$
$M_1=\frac{M_2V_2}{V_1}=\frac{2.0\ M\times250\ mL}{100.0\ mL}$
Answer:
$5.0\ M$
