Ionic compounds are substances that are made up of ions. There is no ionic formula as carbon and oxygen do not form an ionic compound.
<h3>What are ionic compounds?</h3>
Ionic compounds are compounds that have two differently charged species that bind together. The positive metal species binds to the negative nonmetal species.
Carbon and oxygen both are nonmetals and cannot form a bond as nonmetals gain electrons and metals donates electrons for the bond formation.
Therefore, no ionic compound is present for carbon and oxygen.

The molarity of a saline solution that contain 0.900 g NaCl (58.44 g/mol) dissolved in 100.0 ml solution is 0.15 M
<u><em>calculation</em></u>
Molarity = moles /volume in liters
volume in liters = 100.0 ml / 1000 = 0.1 L
moles = mass÷ molar mass
= 0.900 g ÷58.44 g/mol =0.015 moles
molarity is therefore = 0.015 moles / 0.1 L =0.15 M
