a stock solution has a concentration of 0.30 m clo2 and is diluted to become a 0.20 m solution with a volume of 0.050 l. what wa
Pavlova-9 [17]

The stock solution has a volume of 0.208L. When diluted, a stock solution with a concentration of 0.30 m clo2 becomes a 0.20 m stock solution with a volume of 0.050.

A three-dimensional space's occupied volume is measured. It is frequently measured numerically with SI-derived units (such the cubic metre and litre) or with other imperial units (such as the gallon, quart, cubic inch). Volume and length are related in how they are defined (cubed).

A highly concentrated stock solution, often prepared as a 10x concentrated solution, can be described as a stock solution since it can be diluted to create a working solution. In order to prepare complex solutions with numerous constituents, stock solutions can also be utilized as a component.

0.3M*v = 0.125M*0.50L

V=0.208L

  B is the midpoint of \overline {AC}         {}          

  D is the midpoint of \overline {CE}         {}          

2. AC = CE, AB = BC, CD = DE        {}      Definition of midpoint

3. AB + BC = AC, CD + DE = CE      {}       Segment addition postulate

4. CD + DE = AC        {}                             Substitution property of equality

5. AB + BC = CD + DE  {}                          Substitution property of equality

6. BC + BC = CD + CD          {}                  Substitution property of equality

7. 2·BC = 2·CD         {}                               Addition of two identical quantities

8. BC = CD  {}                                            Division property of equality

9. BC ≅  CD     {}                                       Definition of Congruence

(2) The two column proof for the triangular geometric figure is presented here as follows;
