# Best answer: What volume of alcohol and volume of water must be mixed?

Contents

HERE IS THE ANSWER. 60% by volume of alcohol solution means,each 100 ml of solution will have 60 ml ethyl alcohol. hence in a 250ml solution of 60% by volume of alchohol and water,alcohol should be 150 ml and water should be 100 ml.

## What volume of ethyl alcohol and water must be mixed together to prepare 250 ml of 50?

Water is 100-60 = 40 ml. Hence in 250 ml solution, 3 parts of 250ml is ethanol and 2 parts of 250ml is water. In total, 5 parts makes 250. So 1 part is 250/2 = 50 ml.

## How many ml of ethanol should be added to 250ml of water?

Let the ml of ethanol be added to water be x. Hence, 200 ml of ethanol should be added to 250 ml of water to obtain a solution containing 80% of volume by volume solvent.

## When 50 ml of ethanol is mixed with 50 ml of water what is a solution form?

If you mix 50 ml of water with 50 ml of ethanol, the total volume actual equals less than 100 ml. The reason the mixture does not add up to 100 ml is because the molecules that make up ethanol are smaller than the molecules that make up water. So, the ethanol molecules cram themselves between the water molecules.

## Why does the volume decrease when you mix water and alcohol?

When the molecules of isopropyl alcohol or methanol slip between the water molecules, the volume decreases as the molecules in the mixed liquid become more compacted.

## What is the percentage by volume of ethyl alcohol?

Ethanol concentration table: what is the percentage by volume or weight?

Concentration of ethanol by weight (w/w) Concentration of ethanol by volume (v/v)
85.0% (w/w) 89.5% (v/v)
89.0% (w/w) 92.5% (v/v)
90.0% (w/w) 93.3% (v/v)
95.0% (w/w) 96.8% (v/v)

## How would you prepare 250 ml of 70 V V of rubbing alcohol?

Answer. You would add enough water to 175 mL of rubbing alcohol to make a total of 250 mL of solution.

## What is the percent by volume of a solution formed by mixing 25ml of isopropanol with 45 mL of water?

What is the percent by volume of a solution formed by mixing 25 mL of isopropanol with 45 mL of water? 35.7% isopropanol solution.

## Is volume conserved when two liquids are mixed?

When one volume of liquid is mixed with another volume of liquid that is less dense than the first, the total volume of the two liquids will not be the sum of the two individual liquids. The molecules of one liquid can fill in the volume between the molecules of another.

## What happens when alcohol and water mix?

When you mix the rubbing alcohol with water, the latter’s molecules make hydrogen bonds with the water molecules. The alcohol dissolves in the water to form a homogenous solution, so you cannot distinguish the alcohol and the water anymore.

## What is the appearance of alcohol and water mixture?

The alcohol and water mixture would look transparent because the alcohol dissolves in water, thus, it became a homogenous mixture. 2. The appearance of the water and cooking oil mixture is that, the cooking oil is above the water and vice versa. 3.

## Is volume conserved when you mix alcohol and water?

Is the volume additive? The Law of Conservation of Mass dictates that the mass is conserved, but is there a Law of Conservation of Volume? No, if you mix 250 mL of water with 250 mL of ethyl alcohol, only about 480 mL of solution results.

## Why is volume not conserved?

Volume is one of those properties which is not conserved, particularly when the reaction involves gases as reactants or products. For example, hydrogen and oxygen react explosively to form water vapor. … (All of the volumes are measured at the same temperature and pressure).

## Does alcohol dissolve in water?

Even though alcohol has one polar area (O–H bond) and a larger nonpolar area (C–H bonds), polar water molecules and the polar area on alcohol molecules are attracted to each other, causing alcohol to dissolve in water.
