Answer:

Explanation:

Molecular equation for the reaction:

HI(aq) + KOH(aq) --> KI(aq) + H2O(l)

Ionic equation

K+(aq) + OH-(aq) + H+(aq) + I-(aq) --> K+(aq) + I-(aq) + H2O(l)

Net ionic equation:

H+(aq) + OH-(aq) --> H2O(l)

What is the percent by volume of alcohol, in a solution containing 24 mL of alcohol dissolved in 90 mL of water?
Dmitry [639]

Answer:

use this formula it will help u .

Explanation:

If 60 ml of ethanol is diluted to a final volume of 400 ml, you create a 35 % ethanol solution.

First, realize that you creating a solution with that contains a polar solute (ethanol) with a polar solvent (water). Remember that "like dissolves like."

If you pour 60 ml of ethanol in a volumetric flask, you add 340 ml of water to dilute this solution to a final volume of 400 ml.

Volumetric flasks are designed to make or dilute solutions to specified final volume.

Since you have 60 ml of ethanol in a total solution of 400 ml, the percentage of ethanol is 35 %.

This result is obtained in the following manner.

ml/400. ml. = .35

.35 x 100% = 35 %
