when 10.0 ml of the 0.50 m solution is diluted to 100 ml as shown, what is the new concentration?
when 10.0 ml of the 0.50 m solution is diluted to 100 ml as shown, what is the new concentration?
Answer
Explanation:
Step1: Recall dilution formula
$C_1V_1 = C_2V_2$
Step2: Identify given values
$C_1=0.50\ M$, $V_1 = 10.0\ mL$, $V_2=100\ mL$
Step3: Solve for $C_2$
$C_2=\frac{C_1V_1}{V_2}=\frac{0.50\ M\times10.0\ mL}{100\ mL}$ $C_2 = 0.05\ M$
Answer:
$0.05\ M$
