Given :
On a shelf sits a bottle of NaCl solutions with a molar concentration of 2.50 M and a total volume of 300 mL. If 15.0 mL of the solution is added to 985 mL of pure water .
To Find :
The molar concentration of NaCl in the new solution.
Solution :
Molarity M is given by :
Now , 1000 ml of NaCl contains 2.5 moles of NaCl .
So , 15 ml of NaCl contains :
New , volume V = 15 + 985 = 1000 ml = 1 L .
So , putting value of n and V in above equation :
Therefore , the molar concentration of NaCl in the new solution is 0.0375 M .
Hence , this is the required solution .
This is genetic engineering.
I hope this helps!
Cheer,s July.
Among the choices given, the correct answer is the first option. Substance X most likely is a crystal, and substance Y most likely is a liquid. Substance X having a fixed volume describes a crystal because crystals occupy a certain volume. Substance Y is a liquid because liquids can still be compressed further in order to attain a more packed <span>structure.</span>
The answers will be 21.5 L N2
Answer:
I believe the answer is the last one answer D: Neutral elements
Explanation:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. ... Ionic compounds are typically neutral. Ionic compounds generally form between elements that are metals and elements that are nonmetals.
