Answer :
Answer: The concentration of ammonia is 0.0286M.
Explanation:
The diluted equation is presented as: [tex]M_{s} V_{s} =M_{d} V_{d}[/tex].
~M= Molarity (labeled as M)
~V= Volume (labeled in L)
~s= stock solution (what you started with)
~d= diluted solution (what you now have)
Now that we have our definitions, we can knowingly plug the information into the formula shown above.
[tex]0.117M*24.4mL=M_{d} *100mL[/tex]
We have the information plugged in, but the volume must be measured into liters, not milliliters. We can fix that by converting it. To convert milliliters to liters, you divide the milliliters by 1000.
[tex]24.4mL/1000=0.0244L[/tex] [tex]100mL/1000=0.1L[/tex]
Now that the volumes are in liters, let's plug that into the equation.
[tex]0.117M*0.0244L=M_{d} *0.1L[/tex]
We are now ready to solve the concentration with this equation!
[tex]M_{d} =\frac{0.117M*0.0244L}{0.1L}[/tex] [tex]M_{d} =0.0286M[/tex]
With all of the steps shown above, we can conclude that the new concentration of ammonia is 0.0286M.
I hope this helps! Pls mark brainliest!! :)
