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.
The hallogens chloride with br
1 mole ------------ 6.02 x 10²³ atoms
? moles ----------- 5.0 x 10²³ atoms
moles = 5.0 x 10²³ / 6.02 x 10²³
= 0.830 moles
hope this helps!

Answer:
Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
Explanation:
The substance having highest positive reduction 
potential will always get reduced and will undergo reduction reaction.
Reduction : cathode
..[1]
Oxidation: anode
..[2]
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the 
of the reaction, we use the equation:
The overall reaction will be:
2 × [1] + 3 × [2] :
Electrons on both sides will get cancelled :
Numbers of electrons transferred in the electrolytic or voltaic cell is 6 electrons.
