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

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
