To solve this we use the equation,

 

M1V1 = M2V2

 

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

 

.675 M x V1 = .25 M x 1.3 L

V1 = 0.48 L or 480 mL

In an experiment to find the concentration of calcium hydroxide in limewater , 25.0 cm3 of limewater needed 18.8 cm3 of 0.0400 m
Andre45 [30]

Answer:

0.01504 mol/dm3

Explanation:

Calcium Hydroxide - Ca(OH)2

Hydrochloric acid - HCl

The reaction between both is given as;

2HCl   +   Ca(OH)2   --> CaCl2  + 2H2O

2   :  1

The relationship between the concentration and volume is given as;

CaVa  /  CbVb = na  /  nb

where a = acid (HCl) and b = base Ca(OH)2

Inserting the values;

0.04 * 18.8  /  (Cb * 25)  =  2 / 1

0.752 / 25Cb = 2

Cb = 0.752 / 50  = 0.01504
