Answer:
Lithium formula=Li+
Oxygen formula=O2(2-)
Explanation:
Quick note: These kinds of formula are really easy to google. Next time, google the chemical name, include the charge and include "formula" and you should get the answer.
The molarity of the solution : 1.2 M
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
mass of NaCl=35 g
Volume of solution = 0.5 L
mol NaCl(MW=58.44 g/mol) :
The molarity :
