Answer:

The answer to your question is below

Explanation:

When we have the number of an element followed by a number, that number is the atomic mass.

Atomic mass is the number of protons plus neutrons.

                              Protons                    Neutrons

Carbon-13                  6                            13 - 6 = 7

Chromium-51            24                          51- 24 = 27

Strontium-88             38                           88 - 38 = 50

Boron-10                     5                            10 - 5 = 5

You have 363 mL of a 1.25M potassium chloride solution, but you need to make a 0.50M potassium chloride solution. How many milli
maxonik [38]

Answer:- 544.5 mL of water need to be added.

Solution:- It is a dilution problem. The equation used for solving this type of problems is:

M_1V_1=M_2V_2

where, M_1 is initial molarity and  M_2 is the molarity after dilution. Similarly,  V_1 is the volume before dilution and  V_2 is the volume after dilution.

Let's plug in the values in the equation:

1.25M(363mL)=0.50M(V_2)

V_2=\frac{1.25M(363mL)}{0.50M}

V_2=907.5mL

Volume of water added = 907.5mL - 363mL  = 544.5 mL

So, 544.5 mL of water are need to be added to the original solution for dilution.
