Answer:
0.5M
Explanation:
The equation for molarity is:
- M =
; where the "M" stands for molarity, the "mol" stands for moles of solute and the "liters" means the volume in liters of solution.
We are given that there are:
- 1.80 moles of NaCl (the moles of solute)
- 3.60 Liters of solution (the volume in liters of solution)
Now we just plug those numbers into the formula and get our answer:
- M=
= 0.5M
After doing the math and dividing the moles of solute by the liters of solution, we get that the molarity of the solution is 0.5M.
Answer: C - B - A - D
Explanation:
-Obtain a flask that is thoroughly cleaned
-Add the desired amount of stock solution
-Add deionized water until the volume reaches the mark on the flask.
- Cap the flask and invert several times to thoroughly mix the solution.
Total number of atoms = 7
Total number of H atom = 5
% of H in ammonium hydroxide = 5/7 ×100 = 71.4 %
Answer:
I don't think you can go on without doing a reaction since you touch really anything so no you can not go without any chemical reaction I think this is the answer
Answer : The concentration of nitrate ions is 0.450 m.
Solution : Given,
Molarity of 
= 0.225 m
The balanced ionic equation is,
From the reaction, we conclude that the 1 mole of produces 2 moles of 
ions. That means the concentration of nitrate ions is twice the value of .
then, 0.225 m of gives 2 × 0.225 of ions
Now the concentration of ions is equal to 0.450 m.
