There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.
To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:
Covalent is followed by ionic, hydrogen, and van der Waals.

Answer
0.9516 grams / mL (50.00 has 4 sig digs.)
Remark
You have a couple of extraneous numbers there. You don't care about anything except the mass of the flask + water/alcohol mixture (88.219 grams). and the mass of the flask (40.638 grams)
Formulas
- mass water/alcohol mixture = mass of the flask with fluid - mass flask
- density = mass / volume
Solution
mass water/alcohol mixture = 88.219 - 40.638 = 47.581
- Volume = 50 mL
- Density = mass / Volume
- Density = 47.581/50
- Density = 0.95162 There are 4 sig digs so the answer should be
- 0.9516
Sodium chloride is made from one sodium atom and one chlorine atom:
Sodium has a charge of +1, or just +.
Chlorine has a charge of -1, or just -.
These balance out.
