What is the final volume in milliliters when 0.918 l of a 44.0 % (m/v) solution is diluted to 21.8 % (m/v)?

1852.844 mL

Explanation:

The volume of 44% solution used to make the mixture = 0.918 L

Let the volume of 21.8% solution used to make the mixture = x L

For 44% acid solution:

C₁ = 44% , V₁ = 0.918 L

For 21.8% acid solution :

C₂ = 21.8% , V₂ = x L

Using  

C₁V₁ = C₂V₂

44×0.918 = 21.8×x

Solving for x, we get:

x = 1.852844 L

Final volume in mL as:

1  L = 1000 mL

Thus, final volume = 1852.844 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.
