Hey I’m not sure but I hope you have a good day today
Ionic bond is a type of bond in which one or more atoms are transferred to another atom which results to two ions with opposite charge. They attract each other.
The atom of another element is removed and then gained by another element which produces a noble gas electron configuration.
Covalent bond is a type of bond in which a pair or more electrons are being shared by the atoms of two elements.
Because of this, the molecules become stable by sharing the electrons thus creating a noble gas configuration for each of the atom.

2.3g of sodium would be needed to create a 100 millimole concentration in one liter.
Given,
Mole of Na+ = 100 millimole
As we know that,
1 millimole = 10 -³ mole
Mole of Na+ in 100 millimoles = 100 × 10 -³ mole
= 0.1mole
<h3>What is Mole? </h3>
Mole is defined as the ratio of mass of Na+ to the molar mass of sodium.
<h3>What is Molar Mass? </h3>
The molar mass is defined as the sum of the total mass in grams unit of the atoms present to make a molecule per mole.
Mole of Na+ = mass of Na + / molar mass of Na +
0.1 = mass of Na + / 22.99 gl mol
Mass of Na + = 0.1 × 22.99
= 2.299 g
Mass of Na + = 2.3 g
Thus, we calculated that 2.3g of sodium would be needed to create a 100 millimole concentration in one liter.
