Answer:
One mole of oxygen atoms has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 10^23 atoms of oxygen.
Explanation:
The proton has a positive charge.
Answer:
I think it will carbon hope it helps
If 0.5 L of solution contains 4 mol
then let 1 L of solution contain x mol
⇒ (0.5 L) x = (4 mol) (1 L)
x = (4 mol · L) ÷ (0.5 L)
x = 8 mol
Thus the molarity of the Sodium Chloride solution is 8 mol / L OR 8 mol/dm³.
