Question

Calculate the molarity of h after 25 ml of 0.025 m koh was added. Remember, the volume has changed and is now the sum of the two mixed volumes?

Answer 1

Answer:

Step-by-step explanation:

Given

initial volume $V_1=25\ ml$

initially Molarity $c_1=0.025\ m\ of\ KOH$

suppose V liter is added to the mixture

To calculate the molarity of diluted solution

$c_1V_1=c_2V_2$

final volume $V_2=V+25$

$0.025\times 25=c_2\times (V+25)$

$c_2=\frac{0.025\times 25}{V+25}$

$c_2=\frac{0.625}{V+25}\ m$
