12.5 mL of 6.0 M KCl is diluted to make a 1.5 L solution. The molarity of the dilution solution is ___ M. (Round atomic masses t
horsena [70]

The molarity of the dilution solution is 0.050 M

<h3>Further explanation</h3>

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

Dilution formula :

\tt M_1.V_1=M_2.V_2

M₁=6 M

V₁=12.5 ml

V₂=1.5 L=1500 ml

\tt 6\times 12.5=M_2\times 1500\\\\M_2=\dfrac{6\times 12.5}{1500}=0.05~M\\\\for~sig.fig\rightarrow 0.050~M

Compare and contrast the properties of acids and bases. include two similarties and two differences.
gtnhenbr [62]
Hello!

Similarities:

-They can conduct electric current because they both are ionic substances.-

-They both form Water and Salt when neutralized. 

Differences:

-Acids release Hydronium ions (H₃O⁺) when hydrolyzed while Bases release Hydroxyl ions (OH⁻) when hydrolyzed. 

-Acids are commonly formed with non-metals (such as Chlorine, Sulfur, Oxygen, and Nitrogen) while Bases are commonly formed with metals (such as Sodium, Potassium, Calcium, and Copper). 

Have a nice day!
