Vinegar is commonly sold as a 5 percent (v/v) solution of acetic acid in water. this measurement means which of the following?
5 grams of acetic acid/100 grams of solution
5 grams of acetic acid/100 grams of water
5 ml of acetic acid/100 ml of solution
5 ml of acetic acid/100 ml of water

The correct answer is : 5 mL of acetic acid/100 mL of solution

Explanation:

The 5 percent (v/v) measurement tells us about volume of the pure acetic acid in an overall solution.

Suppose in 1000 mL of solution , the volume of acetic acid be x

x = 50 mL

Similarly in 100 ml of solution, let the of acetic acid volume be y.

y = 5 mL

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
